Description

  The present invention is a water faucet used for a bathtub, a sink, a hand shower, and the like, and includes a plug body, the plug body being at least one supply port and discharge port for water, and between the supply port and the discharge port. The water channel relates to a water faucet that is surrounded by a water guide that is at least partially disposed within the body of the plug.

  One known faucet is described in DE 10 2004 048 900. The problem with the known faucet is to send water, such as a waterfall, which gains momentum with air, to the discharge side. In this case, it turned out that it was difficult to send out water like a fan-shaped waterfall that was constant and non-uniform.

  Accordingly, an object of the present invention is to solve the problems caused in the known prior art and to form a uniform discharge with no particular unevenness of water such as a waterfall.

  According to the present invention, this problem is solved by the configuration described in the characterizing portion of claim 1.

  Further preferred embodiments of the invention are set out in the dependent claims. It is pointed out that the features individually recited in the dependent claims can be combined with each other in any technically meaningful form and define another configuration of the invention. Further, the features recited in the claims are more fully described in the specification, wherein another preferred embodiment of the invention is shown.

  According to the invention, this object is based on the superordinate concept of claim 1, wherein the water guide comprises a water flow having a central flow in the center of the water guide and a lateral flow in the side region, Is solved by a faucet characterized in that it is provided with turning means for generating a turbulent flow state in the lateral flow. In the present invention, it has been found that various flows are formed in the area of the water guide in the faucet. Of these flows, one is a central flow and the other is a side flow. The problem arises due to the different flow rates of the lateral and central flows. In this case, the kinetic energy of the flowing water is partially disturbed by the turning means for providing the turbulent flow state of the water guided in the lateral flow in the lateral region of the water guide. Is converted to a flow, thus reducing the flow rate. Since the lateral flow velocity is usually higher than the central flow velocity, this can provide an adaptation of the flow velocity between the lateral flow and the central flow, and thus the overall water flow. A stream of water with uniform direction and velocity can then be developed into water like a wide waterfall. Water like a waterfall is discharged uniformly at the discharge port, and the shape of water like a waterfall is still maintained for a long time after discharge. In the present invention, the shape of water such as a water discharge image or a waterfall can be formed over a wide pressure range of inflowing water, and therefore the present invention is less susceptible to fluctuations in water pressure. The faucet can therefore be used reliably at a water pressure of 0.5 bar to 8 bar, preferably 0.5 bar to 6 bar.

  Particularly preferably, the present invention is used in connection with a faucet in which the flow-through cross section of the water guide expands or widens in the direction of the outlet. Enlargement is understood on the one hand as the cross-sectional area of the throughflow cross-section expanding. According to this, in such an expanding through-flow cross-sectional area, the aforementioned problems arise from the different flow rates of the lateral flow and the central flow. On the other hand, the same effect is observed when a strong enlargement of the once-through cross-section to a certain size is made, regardless of the area of the once-through cross-section. This enlargement is obtained, for example, by a change in the flow-through cross-section from a circular water inlet to an elongate but wide water outlet instead. Such very wide water outlets, in which the width of the discharge port expands more than twice the width of the supply port, are found in water showers such as waterfalls or other water faucets such as waterfalls. There, the expansion of the spread is caused by an increase in the width of the discharged water stream. With just this kind of faucet, flow equalization can be achieved in the side flow and / or in the central flow by the turning means according to the invention.

  Preferably, the present invention is used for water guides that are formed in a generally triangular or trapezoidal shape or that have parallel sidewalls.

  While known plug bodies are usually manufactured from alloys, it is further preferred to form the water guide from a plurality of parts, preferably as plastic parts. Such plastic parts are light weight, have a long life, are inexpensive to manufacture, and have a biological advantage especially when providing drinking water. This is because plastic parts do not transfer alloy components or coating components to water.

  In order to generate the turbulent flow state as efficiently as possible, it is preferred that the diverting means is arranged completely or partially in the water flow and preferably has a basic shape of a pin shape or a cylinder shape. It turned out that. Especially in the lateral region of the water guide, this kind of cylinder-shaped or pin-shaped turning means can easily be provided in plastic parts. A particularly good effect is obtained if the geometric axis of the pin-shaped or cylinder-shaped turning means is selected substantially perpendicular to the direction of water flow. This is because turbulence can be generated particularly efficiently.

  In this case, it is particularly simple if the turning means are formed in the lateral flow and at the same time as an integral part of the side wall of the water guide. Such a configuration can be realized particularly easily with plastic injection-moulded parts.

  For certain types of faucets, it has proved particularly advantageous if additionally at least one further turning means is arranged in the main flow. For example, if a water guide is used in which the water flow is greatly diverted after passing through the supply port (this is the case, for example, in the case of vertical inflow or subsequent horizontal diversion), Different flow rates occur. By using additional turning means in the main flow area, this kind of faucet additionally reduces the main flow speed in addition to the turning means provided in the side flow. And equalization is obtained. The turning means provided in the main flow may be configured, for example, in the form of a web (bridge), which selectively fills the height of the through-flow cross section selectively and additionally. Velocity equalization is caused by the generation of turbulent flow. In this case, it is preferable for the stabilization of the water guide that the diverting means provided in the main flow extends over the entire height of the water guide and that the upper and lower parts of the water guide are additionally mechanically coupled. . Such a mechanical connection may be formed by friction welding, plug-in, gluing or locking, for example in turning means. Thereby, the mechanical stability of the water guide can be reliably ensured even with a larger water flow.

  It is further preferred if the diverting means used is constructed in a labyrinth shape and exerts a flow diversion in at least two directions. This labyrinth-shaped turning means may be arranged in the lateral flow as well as the central flow, if necessary. This arrangement is preferably performed at a point where a flow rate that is particularly high and different from the average flow rate occurs. In the case of flow diversion in two directions, the water flow can flow through the left and right sides of the diverting means and is diverted in that case. If there is a turning means in the upper part of the water guide and in the lower part of the water guide that is simultaneously displaced from each other and does not extend over the entire height of the flow-through cross section, in addition, the turning in the third direction is Is possible. In this case, the third direction is a vertical direction, thereby forming a three-dimensional labyrinth.

  Hereinafter, the present invention and the technical surrounding environment will be described with reference to the drawings. Although particularly preferred embodiments of the present invention are shown in the drawings, it should be pointed out that the present invention is not limited thereto.

It is sectional drawing of the water tap by this invention. It is a bottom view of the water tap of FIG. It is a side view of a water guide. It is a figure which shows the upper part of the water guide by this invention. It is a figure which shows the lower part of the water guide by this invention.

  FIG. 1 shows a cross-sectional view of a faucet 1 according to the present invention. The faucet 1 is composed of a stopper body 2, and a water guide 3 composed of two parts is disposed in the stopper body 2. The water guide 3 includes an upper portion 4 and a lower portion 5. The faucet 1 further includes a supply port 6 and a discharge port 7. A water channel 8 is defined between the supply port 6 and the discharge port 7, and the water channel 8 extends partially inside the water guide 3 and is surrounded by the water guide 3. A rectifier 9 is further arranged in the area of the discharge port 7, and the rectifier 9 additionally leveles the discharged water flow 10 again immediately before water discharge. A pin 111 is formed on the upper portion 4 of the water guide 3, and the pin 111 is located on the side wall 12. Another pin 112 is located at the center of the lower part 5, and the pin 112 is arranged at the center of the water guide 3 in the flow direction and is in phase with the offset pin 113 of the upper part 4 which is also arranged at the center. It forms a labyrinth-like structure. In the illustrated embodiment, it can be seen that the inflowing water flow must pass to the left and right beside each pin 112 because the pin 112 in the lower portion 5 reaches the upper portion 4. The pins 111, 112, and 113 form the turning means 12, respectively. The diverting means 12 is used to convert the kinetic energy of the incoming water into a turbulent flow, whereby a reduction in the flow velocity is achieved. In this case, the turning means 12 is arranged on the side wall 12 at the center, that is, on the cross section. In addition to the pins 111, 112, 113, an elongated turning means 14 is also used. The elongated diverting means 14 is used to adapt the flow rate of the central flow 15 occurring on the cross section to the remaining flow rate.

  In FIG. 2, a faucet 1 having a stopper body 2 is shown in a bottom view. The discharge port 7 in the lower part 5 of the water guide 3 can be seen well. A rectifier 9 is located at the discharge port 7. In the illustrated embodiment, the water guide 3 is formed in a substantially triangular shape. In this case, a central flow 15 is formed in the center, and a side flow 16 is formed in the side region 18 of the side wall 12. Side flow 16 is indicated by dashed arrows. Here, it has been found that the central flow 15 has a higher flow rate than the normal side flow 16 in the present invention. This speed difference continues to the discharge port 7 where the water flow 10 impedes water discharge like a monotonous waterfall.

  FIG. 3 shows a side view of the water guide 3 with an upper part 4 and a lower part 5 according to the invention. The water guide 3 can be particularly suitably manufactured as a two-part plastic injection molded part.

  In FIG. 4, the upper part 4 of the water guide 3 is shown as a single part. The pin 111 is located in the region of the side wall 12 and is incorporated in the upper part 4. The pin 111 has a substantially cylindrical basic shape that enters the side wall 12. In the center of the upper part 4, an additional long and thin turning means 14 is additionally located. The narrow diverting means 14 enters on the one hand through the supply port 6 and subsequently the central flow 8 which is strongly deflected by 90 ° enters the pins 112 and 113 formed in a labyrinth shape in the central area of the water guide 3. Used to slow down the central flow 8 before Since the upper part 4 and the lower part 5 are plastic injection molded parts, the upper part 4 and the lower part 5 can be welded or glued together in a particularly simple manner. At this time, the elongated diverting means 14 provides the possibility of providing an additional coupling part in the center of the water guide 3, whereby the installation of the coupling part provides sufficient strength even in the case of a large amount of water flow. To do. Installation of the connecting portion is possible because the long and thin turning means 14 is in direct contact with the lower portion 5 based on its structural height.

  Finally, FIG. 5 shows the lower part 5 with the rectifier 9 as a single component. The pin 112 placed in the central area is well seen. The pins 112 form a labyrinth. Therefore, before the water 10 is discharged from the faucet 1 through the rectifier 9 by the pins 112 and 113 arranged in the central area, the long and thin turning means 14 and the pin 111 provided in the side flow in the side wall 12. The flow rate of the flowing water is particularly effectively equalized.

  The present invention as a whole is not limited to the illustrated embodiment. Rather, it is noted that many variations of the invention are possible within the scope of the claims. Thus, for example, instead of the pin-shaped geometry described, entirely different suitable turning means may be used whose number, position and geometry may differ from the illustrated embodiment.
