Description

  The present invention is a structural unit for a sanitary facility, and the structural unit is inserted as an insertion cartridge into a fluid guide path of an outlet plug or a faucet plug for a sanitary facility, and includes a casing and a water flow regulator. , As well as a type having an upstream mounting mesh.

  A component unit or piping facility unit for a sanitary facility is known, for example, from WO 2004/038112 A1. Although known components for hygiene equipment have been promoted, there is room for improvement.

  The object of the present invention is to improve a component unit formed as a built-in part for a sanitary installation so that the component unit can be manufactured easily and economically and has a reliable function. That is.

  In order to solve the above-described problem, in the configuration according to the present invention, the casing has a male screw on the outer periphery, and the male screw is screwed into the female screw of the outlet plug, and is adjacent to the downstream side of the male screw. A ring seal is arranged, and the length of the casing is defined so that the male thread and the adjacent ring seal can be arranged on the casing, and a water flow dividing portion connected to the casing is arranged on the upstream side. It is.

  The component unit according to the invention consists essentially of two main components (main components) that can be manufactured relatively easily, namely a casing and a water flow segment, which are joined together. Forming a water flow regulator. The water flow dividing portion is configured to divide or divide one incoming water flow into a plurality of divided flows.

  In order to achieve a rugged construction in an embodiment of the invention, the water split part and the casing are partially fitted together in the operating state, i.e. in the assembled state, in the fluid flow direction or in the longitudinal direction of the component unit, i.e. They are partially nested with each other, and an annular step portion is provided on the outer periphery of the water flow dividing portion or the inner periphery of the casing, and the annular step portion is in contact with the end face region of the casing or the water flow dividing portion. It has become. In another embodiment, the water split and the casing are only partially engaged with each other in the axial direction. Such partial engagement or fitting between the components creates a horizontal separation surface between the water split portion and the casing, i.e. these components are not in the direction of water flow, but in the horizontal direction. They are in contact with each other in the plane and act to prevent leakage without the need for additional O-rings or similar ring seals. High sealing or sealing without an additional ring seal between the water split part and the casing is assisted by the provision of an annular step around the water split part or casing in an advantageous embodiment. The portion comes into contact with the end face region of the counterpart component. This eliminates the need for complicated seals at the water flow divisions. The water that has reached the periphery of the water split will flow into the normal water flow. The embodiment is achieved with few components and is extremely compact. Furthermore, the construction height is small, and a high degree of freedom in designing the outlet plug or faucet can be obtained.

  In another embodiment, a perforated plate (perforated plate) is integrally formed on the downstream side of the casing. The component unit (functional unit) based on this embodiment has a downstream perforated plate integrally formed with a casing screwed into an outlet plug (water tap or mixing tap), and the perforated plate is broken. It is used as a prevention means and effectively prevents undue pressure that is exerted on the components in the casing and leads to leakage.

  Particularly advantageously, an annular step is provided in the water flow dividing part, in particular on the outer periphery of the water flow dividing part, so that the annular step is in contact with the upstream end face region of the casing.

  In another advantageous embodiment, each of the casing and the water splitting part that can be coupled to the casing preferably has an annular locking molded part extending around the entire circumference. Are engaged with each other in the assembled state. Thereby, both components (casing and water split) are simply joined or joined together based on the clip and separated from each other if necessary. The holding element (holding member or holding means) provided integrally with the component parts to be coupled to each other eliminates the need for an additional component member for bringing both component parts together. The structure is simplified and the height or size of the structure is reduced.

  The male thread and ring seal provided on the casing part allow the direct installation of the outlet plug for the sanitary installation into the water flow channel without the need for an intermediate holder with male thread and ring seal. . This simplifies manufacturing and assembly or assembly.

  The separation between the casing part and the water split part is particularly advantageous if the functional characteristics of the water regulator are not changed. For this purpose, between the perforated plate of the casing, preferably formed as a honeycomb-shaped plate, and the perforated plate of the water flow segment, for one or more inserts or inserts in the form of a grill or grid An intermediate space is provided.

  The length or dimension of the casing is defined such that an external thread and a ring seal directly adjacent to the downstream side of the external thread can be arranged on the casing, and the casing has an edge directly following the upstream side of the external thread. As a result, an extremely compact structure is obtained. The compact component unit is formed so that the total height of the insertion cartridge in the fluid flow direction (axial direction of the component unit) is about 1.5 cm including the mounting mesh.

  Advantageously, the spacing between the outlet plug female thread and the outlet plug opening or outlet is smaller than the spacing between the casing ring seal and the inner end of the casing male thread. As a result, when the component unit is assembled, the screw coupling portion is engaged with each other before the ring seal enters the opening when the insertion cartridge 2 is unscrewed from the outlet plug 4 and taken out. Thus, particularly manual assembly of the component units is very simple. Upon removal or unscrewing on the other side, the ring seal is moved out of the outlet plug seat by the rotation or unscrewing of the component unit before the screw coupling is removed and disengaged. Such a screw coupling means is particularly advantageous when the insertion cartridge is arranged in the outlet portion of the outlet plug over the entire height of the insertion cartridge as a fully insertable insertion cartridge that is hidden from view.

  In an advantageous embodiment, the water splitting part has, on the upstream side, a fitting opening (mounting opening) for receiving the mounting mesh, said fitting opening being defined by an outer annular wall and a support step. The holding element (holding member or holding portion) for fixing the mounting mesh is formed as a locking element (locking portion). For this purpose, the outer annular wall has an undercut portion on the inner periphery. And the outer peripheral edge of the mounting mesh preferably has an annular locking projection that engages into the undercut. As a result, the mounting mesh is clipped to the water flow dividing portion from above, and is securely connected to the water flow dividing portion. Such means contributes to reducing manufacturing and assembly costs on one side and allows for rapid manual or automatic assembly of the mesh on the other side.

  Additional fixing of the clipped mounting mesh is performed upon assembly into the outlet plug. For this purpose, at least a part of the annular wall (ring wall) on the upstream side of the water flow dividing portion and the outer peripheral edge of the mounting mesh forms a stopper that comes into contact with the insertion stopper provided in the outlet plug at the assembly position. It has become. In this case, the insertion stopper in the outlet plug partially or completely covers the mesh edge, so that the mounting mesh is securely held even under adverse conditions. .

  In order to further simplify the production of the component unit according to the invention and reduce the number of components required, in an advantageous embodiment the casing is fitted with a perforated plate integrally formed downstream of the water flow regulator. It is formed as a component.

  In another advantageous embodiment of the invention, the water split part is formed as a component of a water flow regulator together with another perforated plate integrally joined to the water split part and / or the water split The portion has a holding member or holding portion for fixing the mounting mesh.

The water flow dividing portion 7 has a fitting opening 21 on the upper side, that is, on the upstream side, and the fitting opening is defined by an outer annular wall 22 and a support step 23. The annular wall 22 has an undercut 24 on the inner periphery, and the outer peripheral edge of the mounting mesh 9 has an advantageously annular locking projection 26 that engages into the undercut 24. ing. As a result, the mounting mesh 9 is clipped into the fitting opening 21 of the water flow dividing portion 7 from the upstream side (side receiving the water flow), and is securely coupled to the water flow dividing portion 7. By providing each of the components to be coupled to each other of the insertion cartridge 2, that is, the casing 5, the water flow dividing portion 7, and the mounting mesh 9, an integral coupling element (a coupling member or a coupling portion) is provided. They are designed to be joined together without the need for additional holders.

  The casing 5 of the insertion cartridge 2 has an outer peripheral contour (outer peripheral contour) formed for engagement with an assembly tool and / or a downstream end surface formed, for example, a downstream end surface having irregularities or grooves. It's okay. In the embodiment, an annular edge 29 formed on the downstream side is provided, and the insertion cartridge is inserted into (attached to) the outlet plug by engaging or rotating the assembly tool with the annular edge, or Removed from outlet plug.
