  The problem underlying the present invention is to provide a hand-held steam device that can be easily manufactured with a simple structure.

  This problem is solved by the present invention in the hand-held steam device mentioned at the beginning as follows. That is, the casing outer wall device has an opening that communicates with the internal space, and a casing insertion portion that closes the opening is disposed in the opening, and a steam discharge portion operating element and the steam valve are operated in the casing insertion portion. At least one of a movable lever element that can act on the steam valve and a child safety device operating element is arranged.

  In the solution according to the invention, a casing insert that closes the opening is used for holding the operating element of the hand-held steam device. In particular, a steam release operating element, a movable lever element and a child safety device operating element are arranged on the casing insert. Thereby, the number of parts can be reduced.

  Therefore, the casing outer wall device can be used as a simple covering member.

  The above configuration simplifies the manufacture of the handheld steam device. Only a few points of component parts or component units need to be joined together.

  In particular, the steam discharge part operating element acts on the lever element. This lever element now acts on the steam valve to open and close it. The lever element serves as a speed change part between the steam discharge part operating element and the steam valve.

  The child safety device operating element is attached to the lever element so that the steam valve operation by the lever element is prohibited when the child safety device operating element is in the locked position and the steam valve operation by the lever element is permitted when in the released position. It is advantageous to act. In this way, for example, a lever element that transmits a pressing force to the pressure release portion operating element to the steam valve can be used for the child safety device. This minimizes the number of parts.

  It is advantageous if the casing insert is provided with a guide for movement of the lever element. Thereby, even if the number of parts is minimized, an optimal function method can be realized.

  It is further advantageous if the lever element lies on the casing insert in such a way that it can swing in at least part of the region, and in particular is arranged in the interior space. Oscillation is realized via the pressure release operating element, so that the steam valve can be operated on the other hand.

  It is further advantageous if the lever element comprises a working area for the steam discharge section operating element, and pressing the steam discharge section operating element against the working area causes the lever element to act on the steam valve to open the steam valve. Thereby, even if the number of parts is minimized and the structure of the hand-held steam device is simplified, optimum driving can be achieved.

  It is particularly advantageous if the steam valve is closed when the lever element is not acting on the steam valve with sufficient force.

  It is advantageous if a return device is provided for returning the lever element to its original position when the steam release operating element is not activated. This allows the handheld steam device to be operated in a safe and optimal manner.

  In particular, the return device contacts the steam valve and / or the lever element in order to cause the return action.

  In one embodiment, the return device includes a spring device. The spring device generates an appropriate elastic return force.

  In one embodiment, the spring device is constituted by the elasticity of the lever element itself.

  It is very advantageous if at least one spring is arranged between the working area of the lever element and the working area of the steam valve. The at least one spring has a sufficient hardness. This spring transmits a force between the working area of the lever element and the working area of the steam valve (the transmission of this force causes the steam valve to open in one direction. In the case of causing an action, the spring also transmits a force in the opposite direction). The at least one spring can vary in height based on the shape of the spring. This compensates for tolerances during the manufacture of the casing via the at least one spring. Even with such finishing tolerances, the operating portion of the steam valve can be reliably functioned.

  It is further advantageous if the first casing outer wall and / or the second casing outer wall has a (partial) opening which is the opening of the casing outer wall device. The first casing outer wall and / or the second casing outer wall includes a corresponding cutout.

  It is very particularly advantageous if the pressure accumulator is held in the casing insert. Thereby, a hand-held steam device having a simple structure that can be easily manufactured is obtained. For example, it is not necessary to fix the pressure accumulator in the casing outer wall device with screws or the like. The fixing is sufficiently achieved only by abutting against the corresponding abutting element, and the shape-fit type fixing is ensured by holding the pressure accumulating device on the casing fitting portion. As a result, the casing insertion portion has a function of holding functional elements (that is, the operation element and the pressure accumulating device) beyond the role of closing the opening.

  It is very particularly advantageous if at least one abutment element for the pressure accumulator is arranged on the first casing outer wall and / or on the second casing outer wall. The contact element prevents the displacement of the pressure accumulating device in the casing outer wall device through its movement preventing action. In addition, by fixing the pressure accumulating device (as a whole) to the casing insertion part, further movement becomes impossible and fixing in the casing is achieved.

  In one embodiment, the pressure accumulator comprises a connecting pipe that is held on the casing insert. As a result, the pressure accumulator is fixed to the casing insertion portion by a simple method.

  In particular, a packing is disposed between the connection pipe and the casing insertion portion in order to prevent liquid from entering the casing at the casing insertion portion.

  In particular, the connecting pipe is provided with a detachable lid that can be accessed from the outside beyond the casing fitting portion. The connecting pipe has an opening that is a maintenance opening. The pressure accumulator can be accessed for maintenance even from the outside of the casing through a closure (especially a safety closure) having a detachable lid. Furthermore, for example, the storage tank of the pressure accumulator can be filled with liquid through the opening of the connecting pipe.

  In one embodiment, a joining surface is assigned to the first casing outer wall and the second casing outer wall, and the first casing outer wall and the second casing outer wall are joined to each other on the joining surface. This simplifies the structure.

  It is advantageous if the opening of the casing outer wall device to which the casing fitting part is mounted is on the joining surface. This provides a simple structure that can be easily manufactured.

  In one embodiment, the direction of insertion of the casing insertion portion into the casing outer wall device is directed to be particularly orthogonal so that it intersects the joining direction between the first casing outer wall and the second casing outer wall. . As a result, a simple structure can be obtained and the number of parts can be minimized.

  In particular, the casing is composed of a first casing outer wall, a second casing outer wall, and a casing fitting portion (only).

  In one embodiment, the opening of the casing outer wall device is dimensioned such that the accumulator can be inserted into the interior space through the opening. This simplifies manufacturing.

  It is advantageous if the casing insert is fixed to the casing outer wall device. This fixing is effected, for example, by means of conformal elements such as screws and / or bolts, and in addition or instead, for example by adhesive bonding.

  A first component unit including a steam discharge unit operation element, a child safety device operation element, and a lever element, and a second component unit including a pressure accumulator are provided, and the first component unit and the second component unit are casings. It is very particularly advantageous if it is arranged and / or held on the insert. In this way, the number of parts can be minimized as a whole, and the handheld steam device according to the present invention can be easily manufactured.

  In one embodiment, the casing insert has a bent or curved shape. In this way, for example, the operation element can be arranged near the grip so that it can be operated with a thumb or the like when the grip is gripped. For example, a detachable lid can be arranged on the casing fitting portion at a position away from such an operating element (in particular, this detachable lid is connected to the pressure accumulator instead of the casing fitting portion). ).

  In one embodiment, the pressure accumulator is held in a first area of the casing insert, and the steam discharger operating element and / or the child safety device is operated in a second area that is bent or curved with respect to the first area. The element is placed. As a result, an ergonomic optimum structure can be obtained.

  In the following description of the preferred embodiments, the present invention will be described in more detail in connection with the drawings.

  A hand-held steam device, depicted in each drawing and designated generally by the numeral 10 in FIG. The casing 12 includes a casing outer wall device 14 having a first casing outer wall 16 and a second casing outer wall 18. The first casing outer wall 16 and the second casing outer wall 18 are joined to each other at a joining surface 20 (FIG. 1). In particular, the first casing outer wall 16 and the second casing outer wall 18 are fixed to each other with screws. A packing may be disposed in a joint region between the first casing outer wall 16 and the second casing outer wall 18.

  The second casing outer wall 18 is covered with the first casing outer wall 16 along the joining direction 22. An internal space 24 is formed in the casing 12. The first casing outer wall 16 and the second casing outer wall 18 are formed in a bathtub shape.

  The hand-held steam device 10 comprises a grip, in particular an arcuate grip 26. The arcuate grip 26 includes a bow portion 28 having a first partial region 30a formed on the first casing outer wall 16 and a second partial region 30b being a second casing outer wall. 18 is formed.

  An opening 34 is formed between the bow portion 28 and the wall 32 of the casing outer wall device 14. The operator can grip the bow portion 28 of the hand-held steam device 10 with one hand, in particular, so that the operator's finger can exit through the opening 34 from the opposite side.

  The casing outer wall device 14 has an opening 36 on the side opposite to the arcuate grip 26. A steam nozzle 38 or an adapter can be detachably disposed in the opening 36.

  In the embodiment shown in FIG. 1, a steam nozzle 38 is disposed in the opening 36 of the casing outer wall device 14. The steam nozzle 38 includes a holder body 40, to which an original nozzle 42 is attached. The holder body 40 is formed in a cylindrical shape. The holder body partially enters the inside of the casing outer wall device 14 at the opening 36.

  One or in particular a plurality of abutment elements 44 are arranged outside the holder body 40. The contact element 44 restricts the holder body 40 from entering the casing outer wall device 14. The casing outer wall device 14 is provided with a ring element 46 in the opening 36. If the position of the steam nozzle 38 on the casing outer wall device 14 is correct, the contact element 44 contacts the ring element 46 and cannot enter the casing outer wall device 14 any more.

  In the contact position corresponding to this, the steam nozzle 38 can be detachably locked to the casing outer wall device 14 via the lock mechanism 48.

  The casing outer wall device 14 includes an opening 50. This opening 50 is located between the steam nozzle 38 or the adapter opening 36 and the arcuate grip 26.

  The casing outer wall device 14 of the casing 12 includes a lower surface 52. The lower surface 52 is configured so that the hand-held steam device 10 can be placed on a table. Correspondingly, the lower surface 52 has a flat surface as an envelope surface. The hand-held steam device 10 is configured as a whole so that the device 10 does not tilt when the hand-held steam device is erected by placing the lower surface 52 on a table horizontal to the direction of gravity.

  The opening 50 of the casing outer wall device 14 is in the region of the joining surface 20. For this purpose, in the region of the joining surface 20, the first casing outer wall 16 is provided with a first partial opening 54a, and the second casing outer wall 18 is provided with a second partial opening 54b. The first partial opening 54a and the second partial opening 54b are combined to form the opening 50. The first partial opening 54 a and the second partial opening 54 b are formed by a cutout portion 56 on each wall 58 of the first casing outer wall 16 to the second casing outer wall 18.

  The casing 12 is closed by a casing insertion portion 58 disposed in the opening 50. In particular, the fitting direction 60 of the casing fitting portion 58 into the casing outer wall device 14 is parallel to the height direction of the casing 12 between the lower surface 52 and the opening 50. The filling direction 60 intersects the joining direction 22 between the first casing outer wall 16 and the second casing outer wall 18, and is preferably at least substantially orthogonal.

  The casing outer wall device 14 is liquid-tightly closed at the opening 50 by the casing fitting portion 58. For this purpose, the casing insertion portion 58 is appropriately joined to the casing outer wall device 14 by, for example, screwing or bonding.

  The opening 50 and the casing fitting portion 58 extend from the area near the latch 62 of the locking mechanism 48 to the range of the arcuate grip 26.

  In particular, the casing 12 includes a casing outer wall device 14 having a first casing outer wall 16 and a second casing outer wall 18 and a casing fitting portion 58. There are no other casing parts.

  On the casing fitting part 58, the operating elements and functional elements of the handheld steam device 10 are arranged.

  The casing fitting portion 58 (FIGS. 4 to 8) includes a first region 64. The first region 64 serves to close the opening 50 in a partial region adjacent to the opening 36 to the latch 62. The first region 64 includes a connection pipe 66. The connecting pipe 66 faces the inner space 24 of the casing 12. A connection pipe 68 on the pressure accumulator 70 (steam kettle apparatus 70) side is fixed to the connection pipe 66. The casing fitting portion 58 holds the pressure accumulating device 70 through the first region 64. The pressure accumulator 70 is located in the internal space 24 of the casing.

  A packing 72 is disposed between the connection pipe 66 in the first region 64 of the casing fitting portion 58 and the connection pipe 68 of the pressure accumulator 70. This serves to close the casing 12 in a liquid-tight manner.

  As an example, the connecting pipe 66 of the casing fitting portion 58 includes a raised region 74 having a vertical portion 76, and the packing 72 is held on the vertical portion.

  An abutment element 78 for the pressure accumulator 70 is arranged on the first casing outer wall 16 and / or the second casing outer wall 18 in the inner space 24 of the casing 12. The pressure accumulator 70 can be fitted between the contact elements 78. Thereby, the shape adaptation part which prohibits the movement of the pressure accumulator 70 in the internal space 24 and fixes the pressure accumulator 70 in the casing 12 is created.

  Movement in the direction opposite to the filling direction 60 is prohibited by the casing fitting portion 58 because the pressure accumulating device 70 is held on the casing fitting portion 58. When the casing fitting portion 58 is mounted on the casing outer wall device 14, the pressure accumulating device 70 cannot move at all in the internal space 24. Further, it is not necessary to fix the pressure accumulator 70 to the casing 12 with screws.

  In manufacturing, the casing outer wall device 14 is made by joining the first casing outer wall 16 and the second casing outer wall 18, for example. The pressure accumulator 70 can be inserted into the internal space 24 of the casing outer wall device 14 through the opening 50. The accumulator is brought into contact with the contact element 78. By fixing the storage device 70 to the casing fitting portion 58 via the connecting pipe 68, the position of the storage device 70 in the casing 12 is finally determined.

  In principle, for example, after the casing outer wall device 14 is opened, the pressure accumulator 70 is disposed on the corresponding first casing outer wall 16 or second casing outer wall 18, and then the first casing outer wall device 16 is moved to the first casing outer wall device 16. When the casing outer wall device 14 is closed by being joined to the casing outer wall device 18 of No. 2 and then the opening 50 is closed by the casing fitting portion 58, the connecting pipe 68 is fixed to the casing fitting portion 58, and so on. It is also possible to do.

  The pressure accumulator 70 includes an opening 80 on the connection pipe 68. This opening 80 is a maintenance opening for the pressure accumulator 70. A lid 82 is attached to the opening 80. The lid 82 closes the pressure accumulator 70. This lid is removable. In particular, this lid is configured as a safety closure. The lid 82 is accessible from the outside of the casing 12 and can be removed or attached. Correspondingly, the first region 64 of the casing insert 58 has an opening 84 assigned to the opening 80. In particular, the opening 84 is larger in diameter than the opening 80 of the connecting pipe 68. The lid 82 can be put over the connection pipe 68 of the pressure accumulator 70 through the opening 84.

  In a preferred embodiment, the casing insert 58 and its opening 84 are configured so that the casing insert 58 only allows access to the pressure accumulator 70 without having a lid 82 securing function. The “coupling” of the casing fitting portion 58 to the pressure accumulating device 70 is performed by holding the connecting pipe 68 by the connecting pipe 66 of the casing fitting portion 58.

  In one embodiment, the casing insertion portion 58 is formed in a bathtub shape in the first region 64. There is a raised edge 86 that surrounds the recess 88. An opening 84 is formed in the recess 88. There is a connection pipe 66 on the back side of the recess 88.

  The lid 82 is at least partially located in the recess 88.

  Next to the first region 64 of the casing fitting 58 is a second region 90. In particular, the second region 90 is bent or curved with respect to the first region (FIGS. 5 to 8).

  The second region 90 is located adjacent to or within the arcuate grip 26 when the casing insert 58 is secured on the casing 12. On the second region 90 are the operating elements of the handheld steam device 10.

  In the second region 90, a steam discharge section operating element 92 is disposed. In particular, the steam discharge unit operating element 92 is configured as a push switch. By depressing the steam discharge unit operating element 92, the operator can open the steam discharge unit.

  In particular, the steam discharger operating element 92 can move the steam discharger operating element 92 with the thumb when the operator holds the arcuate grip 26 of the handheld steam device with one hand. Are arranged as follows.

  A child safety device operating element 94 is further arranged in the second area 90. The child safety device operating element 94 is configured as a slide switch or a rocker switch, for example. The child safety device operating element 94 has a forbidden position 96 and a release position 98. In the prohibition position 96, the steam discharge portion operating element 92 cannot act to open the steam valve 100, and steam discharge is prohibited. On the other hand, in the open position 98, the steam discharge portion operating element 92 can act to open the steam valve 100.

  There is a steam valve 100 on the pressure accumulator 70. The steam valve 100 includes a valve body 102. The valve body 102 is disposed in the valve housing 106 so as to move in the forward / reverse direction 104. This forward / reverse direction 104 is the operation direction of the steam valve 100.

  The forward / reverse direction 104 intersects the lower surface 52 of the casing 12 and is particularly orthogonal. The forward / reverse direction 104 is at least substantially parallel to the filling direction 60.

  In a state where no force is received, the valve body 102 prohibits the passage of steam. On the other hand, when a force is applied and the valve body 102 moves in the valve housing 106 accordingly, the vapor discharge portion is opened. This steam can be supplied from the pressure accumulator 70 to the opening 36. Therefore, a (steam) pipe is appropriately disposed between the valve housing 106 and the opening 36.

  The casing insert 58 has a lever element 108 in particular in contact with the second region 90. The lever element 108 is swingably disposed on the casing fitting portion 58. The entire lever element 108 or only a part of the lever element 108 may be swingable. This swingability can be realized by using an appropriate connecting device or by the elasticity of the lever element 108 itself.

  The valve body 102 is provided with an action area 110 (see FIGS. 11 to 13), in which the lever element 108 can act in the (anti-) action area 112.

  The valve body 102 is supported on the valve housing 106 via the spring device 14 (FIGS. 12 and 13).

  The spring device 114 is arranged and configured so that when the valve body 102 is in a position where it does not receive force, the valve body 102 is in a closed state and is pushed toward the casing insertion portion 58. When the valve body 102 is pulled away from the valve seat 116 against the action of the spring force of the spring device 114, the steam valve 100 is opened. This force is applied via the steam discharge part operating element 92, transmitted via the lever element 108, and applied to the working area 110 of the steam valve 100.

  The lever element 108 has another working area 118. When the steam discharge portion operating element 92 acts on the action area 118, the lever element 108 swings in the action area 112 for acting on the steam valve 100.

  The working area 118 of the lever element 108 is connected to the child safety device area 120, in particular integrally connected. The child safety device area 120 of the lever element 108 is assigned to the child safety device operating element 94. The child safety device operating element 94 can act on the child safety device area 120.

  The lever element 108 and the child safety device area 120 are such that when the child safety device operating element 94 is in the forbidden position 96, the lever element 108 does not swing at all or sufficiently in its working area 112, resulting in the opening action of the valve body 102. It is configured so as not to be allowed. For example, in the child safety device region 120, the swing axis of the lever element 108 changes in accordance with the switching between the prohibition position 96 and the release position 98, and the force that can be input through the steam discharge portion operation element 92 is insufficient at the prohibition position 96. Thus, it is configured such that sufficient oscillation does not occur.

  A spring device 122 is arranged between the working area 110 of the steam valve 100 and the working area 112 of the lever element 108. The spring device includes a single spring, such as a spiral spring. For example, the spring is radially fixed to a groove (especially a ring groove) of the action region 110 and a groove corresponding to the groove of the action region 112, particularly a ring groove.

  The spring device 122 has an appropriate hardness to enable transmission of force from the lever element 108 to the valve body 102.

  By providing the spring device 122, the working area 110 can be separated from the working area 112, that is, it is not necessary to make the two mechanical contact directly. Thereby, the manufacturing tolerance at the time of manufacture of the casing 12 and the casing fitting part 58 can be compensated. The spring device 122 compensates for this tolerance.

  In one embodiment, the lever element 108 includes a first side 124a and a second side 124b. The action region 112 is disposed between the first side portion 124a and the second side portion 124b. The first side portion 124 a and the second side portion 124 b extend from the side of the working region 112 so as to be separated from each other to the left and right.

  Each of the first side portion 124a and the second side portion 124b includes a contact surface 126, and is in contact with the opposing surface 128 through this surface. The facing surface is formed on the casing fitting portion 58. For example, this surface is formed on the first region 64 near the connecting pipe 66.

  A contact portion for moving the lever element 108 in the internal space 24 of the casing 12 is formed by the contact between the contact surface 126 and the facing surface 128.

  The lever element 108 is assigned a return device that lifts the lever element 108 to its original position when the steam discharge section operating element 92 is released. For this purpose, a dedicated return device may be assigned to the lever element 108. For example, a spring device that is molded with the lever device 108 can be provided. Further, the lever element 108 itself may have elasticity, and the return operation may be generated by its own elasticity after the vapor discharge section operating element 92 is released.

  In one embodiment, the spring device 114 of the steam valve 100 is also used to return the lever element 108. When the operator pushes the steam discharge section operating element 92 with a sufficient force, the action area 112 of the lever element 108 pushes the action area 110 of the steam valve 100, the valve body 102 is pulled away from the valve seat 116, and the valve opens. When the force is released, the valve element 102 is pushed back by the spring device 114 and is pressed against the valve seat 116. At this time, the working area 110 also moves, so that the lever element 112 can be pushed back to the starting position (non-actuated position).

  The handheld steam device 10 functions as follows.

  The casing 12 includes a first casing outer wall 16, a second casing outer wall 18, and a casing fitting portion 58. A casing fill 58 holds all important functional parts and operating elements of the handheld steam device 10. In particular, a steam discharge part operating element 92 and a child safety device operating element 94 as operating elements are arranged in the casing fitting part 58. Furthermore, a lever element 108 is arranged in the casing fitting 58. These elements (steam discharger operating element 92, child safety device operating element 94 and lever element 108) form the first component unit of the handheld steam device. This first component unit is completely arranged in the casing insert 58.

  The pressure accumulator 70 is a second component unit of a hand-held steam device. This second component unit is also held by the casing insertion portion 58.

  The casing fitting portion 58 relatively fixes both the first component unit and the second component unit on the casing 12. The portion of the casing outer wall device 14 in the casing 12 is merely a covering of these constituent units. Fixing on the casing 12 is provided by a casing insert 58 (in conjunction with the abutment element 78 for the accumulator 70).

  The handheld steam device 10 as described above can be easily manufactured. In manufacturing, the first component unit is first fixed to the casing fitting portion 58. Next, the second component unit is fixed to the casing insertion portion 58. This second component unit is inserted into the casing outer wall device 14. By finally fixing the casing fitting portion 58 to the casing outer wall device 14, final fixing of the second component unit to the casing 12 is also achieved.

  In one embodiment, the opening 50 of the casing outer wall device 14 is formed through the first opening 50 when the first casing outer wall 16 and the second casing outer wall 18 are joined to complete the pressure accumulating device 70. Is sized so that it can be inserted into the internal space 24.

  At that time, the pressure accumulating device 70 may be held in advance by the casing fitting portion 58, or the casing fitting portion 48 may be fixed to the pressure accumulating device 70 and to the casing outer wall device 14 later.

  In principle, after the pressure accumulating device 70 is put into the first casing outer wall 16 or the second casing outer wall 18 and the casing outer wall device 14 is closed, the casing fitting portion 58 is fitted in the filling direction 60. Is possible.

  The solution according to the invention minimizes the number of parts. Moreover, the manufacture of the handheld steam device is facilitated.

  Even if there is a manufacturing tolerance, the steam valve 100 can be reliably operated by the spring device 122. This in turn makes manufacture easier.

  The pressure accumulator 70 includes a storage tank 130 (pressure cooker). The storage tank includes a first region 132, a second region 134 disposed on the first region, and a third region 136 disposed immediately below the first region 132. The storage tank 130 is fixed via the contact element 78 on or near the lower surface 52 in the internal space 24 of the casing 12 via the third region 136.

  In one embodiment, the third region 136 is removable from the first region 132, for example, the first region 132 and the third region 136 are joined together in a fluid-tight manner with screws or bolts.

  A heater 138, particularly an electric heater, is disposed on the third region 136. Thereby, vapor | steam (especially water vapor | steam) can be generated from the liquid (especially water) in the storage tank 130, and it can be stored there in the state which can be pulled out.

  An electrical connection device 140 is disposed in the casing 12, and the heater 138 can be connected to a power feeding network through the casing 12, whereby necessary power can be supplied to the heater 138.

  In one embodiment, the third region 136 includes a flange 142a and the first region 132 includes an opposing flange 142b. The first region and the third region are coupled to each other via the flange 142a and the opposing flange 142b.

  A connection pipe 68 having an opening 80 is formed in the second region 134. Correspondingly, a lid that is an element for closing the pressure accumulator 70 and the maintenance opening 80 is also attached to the second region 134 of the storage tank 130.

  The steam valve 100 is on the first region 132.

  A recess 144 is formed on the storage tank 130 between the second region 134 and the first region 132. The recess is defined by the first wall 146 in the first region 132 and the second wall 148 in the second region. The first wall 146 and the second wall 148 intersect each other (for example, orthogonal). These walls are connected to each other.

  The steam valve 100 is on the first wall 146 of the first region 132, particularly at a position remote from the second wall 148 of the second region 134.

  In the recess 144, the storage tank 130 includes a stepped portion 150. This step 150 is indicated by reference numeral 150 in FIG.

  The steam valve is oriented at least approximately parallel to the connecting pipe 68.

  The opening 80 of the pressure accumulator 70 in the second region 134 has an opening direction 152. The opening direction 152 intersects the lower surface 52 and is particularly orthogonal.

  The steam valve 100 is disposed in the recess 144 in parallel with the opening direction 152. The forward / reverse direction 104 of movement of the valve body 102 within the valve housing 106 is at least substantially parallel to the opening direction 152 of the opening 80.

  The forward / reverse direction 104 and the parallel extending direction of the steam valve 100 are oriented so that they intersect (especially orthogonal) with respect to the joining direction between the first region 132 and the third region 136 in particular. ing.

  The storage tank 130 has a roof 154 on the opening 80. The concave portion 144 is configured such that the steam valve 100 protrudes from the roof portion 154 in the opening direction 152 at all or slightly with respect to an appropriate height of the steam valve 100. In particular, the steam valve 100 projects only up to 5 cm above the roof portion 154.

  Thereby, the height dimension (in the height direction parallel to the forward / reverse direction 104 to the opening direction 152) of the pressure accumulator 70 is kept small. Thereby, the height dimension of the corresponding casing 12 is also kept small. Thereby, the hand-held steam apparatus 10 which can be held by hand is realizable.

  The steam valve 100 includes an exhaust connection 156 for steam (see, for example, FIG. 9). The exhaust connecting portion 156 is disposed on the side surface of the valve housing 106 and is located so as to intersect (for example, orthogonally cross) the forward / reverse direction 104 to the opening direction 152. In particular, the connecting portion is disposed in the recess 144. A steam discharge pipe is connected to the opening 36 via the exhaust connection portion 156.

  A discharge opening 160 is formed in the recess 144 on the first wall 146 (see, for example, FIG. 12). A steam valve 100 is disposed on the discharge opening 160. A valve housing 106 surrounds the discharge opening 160 outside the first wall 146. Steam can be discharged through the steam valve 100 through the discharge opening 160. The discharge opening 160 forms a connection path through which fluid flows to the internal space 162 of the storage tank 130. In a region where the discharge opening 160 is present, the cylindrical element 164 is disposed in the internal space 162. A part of the wall of the cylindrical element 164 is formed by the wall 166 of the first region 132 of the storage tank 130 corresponding thereto. A portion 168 of the tubular element 164 is connected to the first wall 146. In one embodiment, this portion 168 extends to the second region 134 to form the second wall 148.

  Due to the tubular element 164, a partial space 170 is formed in the internal space 162 before the discharge opening 160. This partial space 170 is partitioned by a damming lattice 172. The damming lattice is fixed to the tubular element 164.

  Further, a pin-like element 174 is disposed in the internal space 162. The pin-like element is in particular fixed to the wall 166 or formed on its surface. The pin-like element 174 holds a damming grid.

  The damming grid 172 is for damaging particles that may be emitted through the emission opening 160. The discharge opening 160 has a smaller cross-sectional area than the partial space 170. The clogging grid 172 prevents the discharge opening 160 or the steam valve 100 from being clogged or damaged.

  A wall 176 is disposed in the internal space 162. This wall extends at least substantially parallel to the opening direction 152 and starts from the second region 134 and enters the first region 132, ie, protrudes from the first wall 146. The wall 176 defines a partial space 178 in the first region 132 and the second region 134. This partial space 178 becomes a steam chamber during the steam generation operation of the handheld steam device 10. This partial space 178 should be free of any or as much liquid as possible.

  Wall 176 begins with ceiling wall 158 and is higher than second wall 148 that extends to inner wall 168.

  A rectifying element 180 is fixed to the pin-like element 174. The rectifying element 180 is a metal plate part in particular, and divides the partial space 178 (including the partial space 170) from other parts of the internal space 162.

  The rectifying element 180 is formed so as to be closed to one or more gaps 182 through which the steam passes. The rectifying element 180 prevents water from entering the partial space 178 as much as possible.

  In one embodiment, the rectifying element 180 is further supported on the damming grid 172 via a support 184.

  The rectifying element 180, in one embodiment, loosely abuts the wall 176 (up to the partial space 178) and / or the inner surface 186 of the wall 166. The one or more gaps 182 may be formed there.

  The width of the gap is in particular between 0.2 mm and 1.0 mm, for example between 0.4 mm and 0.6 mm.

  In one embodiment, the rectifying element 180 has one or more stripping edges 188. The stripping edge 188 serves to “quiet” the liquid flow beneath the rectifying element 180 in order to sufficiently avoid liquid ingress into the subspace 178.

  In one embodiment, the rectifying element 180 includes a first region 190 and a second region 192. The second region 192 is curved or bent with respect to the first region 190. Then, a peeling edge 188 is formed between the first region 190 and the second region 192.

  As an example, the second region 192 points to the wall 176 and is in contact with, for example, this wall (especially with a gap 182).

  During operation of the hand-held steam device 10, the storage tank 13 is first filled with liquid (especially water) (particularly partially filled). In particular, the liquid is injected into the storage tank 130 through the opening 80. During the steam generation operation, the lid 82 is fixed to the opening 80. By operating the heater 138, the liquid is evaporated. The storage tank 130 has a liquid storage space 194. The tank further has a steam storage space 196. The relative sizes of the storage spaces 194 and 196 are variable, and vary depending on the amount of liquid used. The subspace 178 is ideally a pure vapor space. Since there is no liquid in this space, only the vapor stays there and can be released.

  A certain minimum distance is provided between the damming grid 172 and the rectifying element 180. For example, it is at least 1 mm.

  In the storage tank 130, during operation, vapor is generated from the liquid via the heater 138 and accumulated therein. When the vapor discharge part operation element 92 is pressed, the vapor discharge part is opened. That is, the valve body 102 is pulled away from the valve seat 116, and the vapor accumulated in the storage tank 130 under pressure flows out through the discharge opening 160 and is appropriately used for cleaning, for example, through the vapor nozzle 38. .

  Because of the rectifying element 180, the handheld steam device 10 can be used in various postures. The opening direction 152 (the height direction of the storage tank 130) need not be parallel to the gravity direction g. A posture inclined with respect to the gravitational direction g can also be adopted. At that time, the rectifying element 180 sufficiently prevents the liquid from entering the partial space 178.

  Since the pressure accumulator 70 is configured to be compact with its height dimension minimized, the dimensions of the casing 12 can also be minimized without having to make a significant compromise with respect to the capacity of the liquid. .

  The pressure accumulating device 70 and the steam valve 100 disposed thereon can be handled as a unit when the handheld steam device 10 is manufactured, and can be held by the casing fitting portion 58 as a whole. The number of parts required is minimized, which in turn makes it easier to manufacture.

  In one embodiment, the steam valve 100 to the important parts of the steam valve 100 (valve body 102, valve housing 106, valve seat 116) are made of a plastic material.

  Even if the hand-held vapor apparatus 10 moves, the liquid surface is calmed by the rectifying element 180, so that the liquid is sufficiently prevented from being drawn into the vapor flow.
