Description

TITLE

Distributor head for a beverage maker

TECHNICAL FIELD The present invention relates to a header for distributing hot liquid over an infusion material in a beverage maker. Such headers are used in particular in coffee heaters often, in which during the coffee making the captured in a filter coffee powder with hot water is poured over.

STATE OF THE ART

For a long coffee makers are known, in which the coffee prepared in that ground, recorded in a filter coffee is brewed with boiling water. The water is heated to a known manner in a water heater. then before there usually increases over a vertical tube and passes into an upper horizontal pipe. This horizontal pipe terminates above the filter. From there, the hot water drips through one or more outlet openings down on the recorded in the filter coffee. The water seeps through the ground coffee therethrough, thereby disengaging this from the flavorings out. The filter serves to pass the finished coffee beverage downwards and withhold the leached coffee powder. the finished coffee beverage dripping finally in a vessel which is arranged below the filter, and which is typically is a cup or a coffeepot by the filter.

The same principle is also often used to prepare other beverages such as tea. then instead of coffee a correspondingly different infusion material, in the case of tea so tea leaves were added to the filter.

Thus, the flavoring agents may be dissolved out of the infusion material from the hot water as completely as possible, is desirable in such beverage makers that the water drips spatially uniformly as possible on the recorded material in the filter infusion. For this purpose, distributor heads are also known which fan out the water stream at the end of the horizontal tube above the filter. Such a distribution head of a coffee maker is disclosed for example in document US 4,354,427. The distributor head shown therein forms a distribution chamber for the incoming water, from which the water drips down through a plurality of outlet openings on the coffee powder. Another such distributor head is described in US 6,244,162.

A problem of such beverage makers is that along the inner surfaces of pipes and cables often dirt particles and debris contained in the water minerals, such as in particular lime accumulate. Particularly problematic these deposits in the often narrow exit apertures of the header are. The hot water often has in this area at a relatively slow flow while it contacts simultaneously with many inner surfaces of the beverage maker. After use, the beverage maker also stay there often are water residue, thereby forming additional deposits. In addition, the outlets may be due to their typically small diameter quickly clogged by debris or closed by the deposits, which can significantly affect the operation of the beverage maker may.

To avoid such deposits, it is proposed in US 6,755,119 to use for the distribution head a polyetherimide material with a low surface porosity. Here, however, the choice of material for the distributor head is severely restricted. In addition, it is proposed that the outlet openings as tubular structures, which each extend from an intermediate surface upward. WO 03/092456 and IE 060,105 headers are described for beverage maker, which can be for cleaning purposes easily disassembled. The fundamental problem, namely that deposits arise in the first place is, but not resolved.

SUMMARY OF THE INVENTION

It is therefore an object of the present invention to provide a dispensing head for a beverage maker in which dirt and lime deposits avoided especially in the region of the outlet openings or the formation of at least slowed down. To achieve this object, a distributor head is proposed, as set forth in claim. 1 It is proposed also a beverage maker with such a distribution head. Advantageous embodiments of the invention are specified in the dependent claims. All local used hereinafter and direction information, such as top, bottom, horizontal, vertical, upwards, downwards etc. header used are to be understood in each case in relation to the direction of gravity for an intended purpose in a beverage maker. Typically, the dispensing head is then placed with its outlet openings directly above the infusion material.

Thus, the present invention provides a header for distributing hot liquid over an infusion material in a beverage maker for disposal, comprising: a housing having an interior with an opening into the interior of the inlet for the liquid and with a plurality of outlet openings from the interior to outside lead.

The housing has at least a first portion, which is made of a first material, and at least a second portion of the liquid-repellent material is made better from a second, compared to the first material. Under a liquid-repellent material is meant a material which is not easily wetted by a liquid. so water runs very well on the surfaces of such materials. The second material is particularly better liquid-repellent than the first material, when the contact angle of the same liquid on the second material is greater than on the first material. Preferably, the contact angle of the liquid on the second material in this case greater than 90 °. The second material may then be referred to as hydrophobic. When infusion material, there may be coffee or tea leaves in particular. When hot liquid water is usually used. The interior of the housing is usually used for holding and guiding the hot fluid which is flowing along a main flow direction from the inlet to the outlet openings. Preferably, the interior of the distribution head is in respect to the liquid with the exception of the inlet and the outlet openings towards the outside closable, particularly preferably liquid-tight manner.

The provision of a second portion, which is made in comparison with the first portion of a better liquid-repellent material, causes a generation of deposits at least avoided or in the housing in the area of ​​the second portion is at least considerably reduced. The second portion is thus particularly preferably in each case arranged at those points of the distributor, which are particularly prone to deposits, and in which deposits especially detrimental to the function of the distributor head. Preferably, the second portion therefore in the form of a liner is on the inside, that is arranged on the side facing the interior of the housing.

Preferably, the second material is softer than the first material formed. The second material typically has a Shore A hardness of 40-80, especially 50- 70. The first material, by contrast, a preferred Shore A hardness greater than 80, more preferably even more than 90 at. The second material is preferably a rubber-like material, in particular preferably silicone.

The surfaces of the second portion may be polished, roughened, or left untreated. Preferably, however, they are polished, in particular preferably even highly polished. The hydrophobicity of the surfaces can be increased. Characterized the formation of deposits is avoided on the surfaces of the second portion, or at least slowed down. In addition to any calcium deposits can be very easy, for example with a cloth, wipe.

The surfaces of the second portion may also be so treated and for example have a corresponding micro- and / or nano-structured surface that they achieve a lotus effect in particular.

Most preferably, the second portion is disposed at least in the region of the outlet openings. The second portion is thus preferably arranged in that region, which in each case adjacent extending between the various outlet openings and directly to this. In addition, the second component is particularly preferably arranged in such a way that it forms in each case the inner surfaces of the outlet openings, so that the liquid comes exclusively with the passage through the outlet openings in contact with the second portion. Preferably, the outlet openings are disposed within an orifice plate. At least one side of the orifice plate, which preferably represents a part of the first portion is preferably coated with the said second material, which particularly preferably extends into the holes of the perforated plate.

Preferably, the outlet openings each have such an internal diameter that drop formation at the exit of the liquid is promoted from the outlet openings out. Specifically, an inner diameter of the outlet openings of less than 4 mm, particularly 1-3 mm, are preferred. If the second material extends respectively in the holes of a perforated plate of the first portion into, the second material there preferably each have a radial thickness of 0.5 - 1 mm, especially of 0.6 - 0.8 mm. The radial thickness extends in the plane of the inner diameter of the outlet openings, that is perpendicular to the inner surface of the Austrittöff Ungen.

Preferably, the second portion in the entire region of the interior is arranged. Most preferably, the second portion thereby covers all towards the interior facing surfaces of the first portion. In addition, preferably also are all inside surfaces of further defining the interior elements, such as closure elements, also made of the second material. In other words, the second portion thus preferably forms all fluid surfaces of the distributor head. Dirt and lime deposits can be avoided throughout the interior or reduced. The first and the second portion of the housing can each in one piece, but also a multi-part be formed. In a particularly preferred embodiment the second portion is molded onto the first portion. The first portion then therefore preferably forms a basic structure of the housing, which is advantageous at least on the inside over-molded in the region of the outlet openings of the second material. In contrast, however, embodiments are conceivable in which the second portion forming the base structure of the housing, which is supported by the first portion and kept in shape.

The interior is preferably adjacent to the outlet openings a distribution chamber for distributing the liquid. The distribution may in particular serve to distribute the liquid over a larger area. The housing may further advantageously comprise a perforated plate, within which the outlet openings are arranged, and from which preferably a substantially continuous side wall extending along a major axis. The distribution chamber is then limited by the perforated plate and the side wall. Due to a typically slow and non-laminar flow of water inside the distribution chamber in each case pointing towards the distribution chamber to the inner surfaces of the perforated plate and the side wall are normally particularly susceptible to deposits. The second portion is preferable, therefore, arranged such that it forms in each case completely these inner surfaces. The first portion of the housing is thus preferably completely covered in the area of ​​the distribution chamber on the inside of the second material.

If the interior of which forms such a distribution chamber for distributing the liquid, preferably, the housing has an inlet channel which opens into an orifice in the distribution chamber. The inlet channel can define in particular the main direction of flow of the liquid in the interior. in an oppositely disposed to the mouth area of ​​the inlet duct, the inlet for the liquid is advantageously formed in the interior. This inlet is advantageously designed as a connecting piece which extends in particular advantageous in substantially the same direction as the major axis of the side wall of the distribution chamber. The nozzle is preferably designed for connection to a riser tube of the beverage maker. the inlet duct is advantageously arranged relative to a perpendicular to the main axis of the side wall of the distribution chamber perpendicular direction inclined. The inlet duct is thus, when the distributor head is intended for use in the beverage maker, advantageously inclined with respect to back in the direction of the distribution chamber of gravity downward direction. The liquid flowing therethrough downwardly, in the direction of the distribution chamber and can not remain lying in the inlet channel or even to the inlet of the distributor head toward zurückfiiessen.

The orifice plate preferably has a back facing towards the distribution chamber, planar first surface which is formed by the first portion, and a back facing the distribution chamber, flat second surface that is formed by the second portion. Here, the first and second surfaces preferably extend in two mutually inclined directions. Here, the second portion can have, in particular in the area of ​​outlet openings have a thickness which continuously decreases preferably with increasing distance from the mouth of the inlet channel. This decreasing thickness of the second portion may, in particular, help to ensure that the fluid continues to flow after their entry into the distribution within that due to gravity and also reaches those outlet openings which removes opposite the mouth of the inlet channel, compared to the other outlet openings farthest are arranged. It is thereby avoided that most of the liquid to pass only flows through the arranged closest to the mouth of the inlet duct outlet openings. The liquid can be thus evenly distributed in the distribution chamber.

Advantageously, on the header of one or more closure elements which are releasably attached to the housing in order to close this outwardly. Access to the interior is possible because for cleaning purposes, for example. If the interior of which forms a distribution chamber, this is advantageous at least accessible by means of a detachable from the housing closure member from the outside. The distributor may include flow elements which are arranged in the region of the outlet openings and project into the interior, in order to distribute the hot liquid. Such flow elements which are preferably arranged in the distribution, if the distributor head has such a particular may serve to direct the liquid in equal amounts as possible to the outlet openings. It can be avoided by when using the beverage maker flow through a total of greater amounts of fluid through certain exit ports than through other, which would have an uneven atomising the infusion material in a row. Preferably, the flow elements are formed exclusively by the second portion. Preferably, the flow elements are also arranged mirror-symmetrically, with the plane of symmetry preferably extends along the main flow direction of the liquid in the interior. The flow elements can have the shape of a wedge whose apex points in that direction of the flow produces the liquid corresponding to the main flow direction in each respective area for flow element towards particular in each case substantially. The wedge is preferably formed of two limbs, which include an intermediate angle of preferably 45 ° to 90 °, particularly preferably of approximately 70 °. The two legs may be particularly formed in its longitudinal direction different lengths, if the respective flow element is located remote from said plane of symmetry. Preference is given to each of which is arranged closer to the symmetry plane leg is shorter. However, the directly arranged on the plane of symmetry flow members preferably have each a shape of a wedge with two equally long legs formed. Preferably, the flow elements each extend over the entire height of the interior.

The first portion of the housing may in particular be integrally formed. but it may also, in order to facilitate the attachment of the second component in the preparation, for example, when it is designed as a lining, having a main part and a mountable on the main body cover. After the manufacture the main part and the cover may then be permanently joined together for example by ultrasonic welding. The cover can, for example form an upper portion of the inlet channel.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the figures 1 to 9, a preferred embodiment of an inventive dispensing head is shown in different views. The distribution head is used for distributing hot liquid over an infusion material in a beverage maker. The infusion material in which it can be, for example, ground coffee or tea leaves is added in such beverage container in a filter and is from above via the distributor head with hot water poured over. The finished coffee beverage flows through the generally tapered from top to bottom through the filter and drops into a disposed below the filter cup or coffee pot from there. The leached coffee powder is retained by the filter. The distributor head serves in particular to the fact that hot water to versprenkeln spatially uniform as possible over the infusion material, so that the flavor substances can be removed from the infusion material from the water in an optimal manner.

The distributor head comprises in the present embodiment, as shown in Figure 1, a housing 1, 2, 3, 4, which is formed by a first portion and a second portion. The first portion is formed by a housing main part 1 and a case cover 2, the second portion by silicone liners 3 and 4. In the present embodiment, the silicone liners 3 and 4 are respectively on the casing main body 1 and the housing cover 2 of the housing 1, 2, 3, 4 molded. The basic form of the housing 1, 2, 3, 4 is thus defined here essentially by the casing main body 1 and the housing cover. 2 The housing 1, 2, 3, 4 forms an inner space 7 which serves to guide the hot liquid. The housing 1, 2, 3, 4 is also in the present embodiment by two closure elements in the form of a closure cap 5 and a sealing plug 6 closable. In the present embodiment, the space 7 is thus limited jointly by the silicone liners 3 and 4 and the sealing cover 5 and the sealing plug. 6

The silicone liners 3 and 4 are preferably each made from a material which is more liquid-repellent than the material of the housing main part 1 and the housing cover 2. Preferably, the material of the silicone liners 3 and 4, a Shore A hardness of about 40 - 80, and the material of the case main body 1 and the housing cover 2 has a Shore a hardness of more than 80. Preferably, the surfaces of the silicone liners 3 and 4 are also respectively polished.

The well recognizable in particular in Figure 6 the housing main part 1 has a Sprenkelelement for distributing hot liquid over the ground coffee in the form of a perforated plate tenth The perforated plate 10 which is circular and formed in a substantially plane here extends normal conditions of installation of the distributor head in a beverage maker perpendicular to the direction of gravity. Inside the perforated plate 10 has a plurality of holes 15 is formed, which are preferably uniformly distributed over the perforated plate tenth The holes 15 allow escape of the hot water from the inner space 7 of the housing 1, 2, 3, 4 to the outside. They are lined in the present embodiment with the silicone liner 3, so that outlet openings 35 are formed. The outlet openings 35 in each case have an inner diameter d, which is dimensioned such that the hot water 35 is preferably incident from the outside of the outlet openings in the form of droplets onto the underneath of the manifold head in the filter taken infusion material. The spatial arrangement of the holes 15 or the Austrittsöfmungen 35 also allows an atomising the infusion material which is as uniform as possible.

Along the peripheral circumference of the perforated plate 10, a circumferential side wall 11 preferably extends upwardly. The transition from the perforated plate 10 to the side wall 11 can, as here, be via a circumferential step. In addition, the side wall 11 may be from below upwardly to have a widening slightly conical shape approximately to half its height, which merges at its upper end with a slight kink in a nearly cylindrical shape of the side wall. 11 Together, the perforated plate 10 and the side wall 11 define the interior space 7 a distribution chamber 70, which serves for distributing the hot water.

In the vicinity of the perforated plate 10 in the side wall 11 a rectangular recess 14 is formed, which extends over approximately half the height of the side wall 11 and extends over an angular range of slightly less than 45 °.

The housing main body 1 additionally has in the present embodiment, an inlet channel 12 which opens out with its front end in the recess 14 of the side wall. 11 The opposite, rear end of the intake port 12 is formed open towards the outside but closed by means of the closing. 6 On the topside of the intake passage 12 is formed over its entire length substantially open and closed by means of the housing cover. 2 From the bottom of the inlet duct 12, two opposite side walls extend upwards. As shown in particular in Figure 2 it can be seen, the side walls of the inlet duct 12 each over a large part of the length of the intake passage 12 at a constant height which is slightly greater than half the height of the recess fourteenth Near the recess 14, the side walls of the intake duct 12 relative to the ground, however, to rise until it slightly above the recess 14 on the side wall

11 end. Above the recess 14, the side walls of the intake passage 12 are connected to each other via a projecting from the side wall 11 of the flange.

In the vicinity of a closable closure plug 6, the rear end of an inlet nozzle 13 extends from the bottom of the inlet duct 12 towards the bottom. The inlet nozzle 13 extends from the bottom of the inlet duct 12 to approximately the height of the perforated plate 10 toward the bottom. With its upper end, the inlet pipe 13 opens into the intake passage 12 and thus forms an inlet for the liquid in the inner space 7. Due to a slight inclination of the inlet channel 12 in the longitudinal direction of this upper end of the inlet nozzle 13 with respect to the direction of gravity slightly above the recess 14. This causes the water after it has passed from below through the inlet nozzle 13, flows due to gravity effect in the inlet duct 12 to the perforated plate 10 out. The inlet channel 12 defines a skin direction of flow of the hot water in the interior 7 of the distributor head, which extends along the longitudinal direction of the inlet channel

12 extends.

Towards the top of the inlet duct 12 is closed by means of the housing cover. 2 The housing cover 2 has a channel 12 complementary to the inlet shape, whereby the sealed with the case cover 2 inlet channel 12 in cross section has a rectangular shape. the housing cover 2 in the manufacture in particular by means of ultrasonic welding is preferred so connected to the inlet channel 12 that it closes this permanently. The provision of a housing cover 2 is used in particular to ensure the accessibility of all interior surfaces of the housing 1 from the outside during production.

The casing main body 1 and the housing cover 2 are preferably made in one piece from a plastic, in particular a polycarbonate. In principle it would of course also conceivable to form the housing cover 2 is directly integral with the housing main part. 1

On the housing main body 1 and the housing cover 2 silicone liners 3 are mounted and 4 respectively. In the present embodiment, these silicone liners cover 3 and 4, all inner surfaces of the housing main part 1 and the case cover 2, and are preferably injection molded to the casing main body 1 or on the housing cover. 2 The silicone liner 3 therefore has an essentially identical configuration as the casing main body. 1 Analogous to the case main body 1 has correspondingly a perforated plate 30 with outlet openings 35, one extending from the perforated plate 30 upwardly extending sidewall 31 having a recess 34 and an inlet channel 32 which opens into the recess 34 and having an inlet nozzle 33rd Likewise, 4, the silicone lining to a substantially identical configuration as the housing cover 2 to which it is attached.

As can be seen in Figure 2, covers the silicone liner 3, respectively, the radial inner surfaces of the holes 15 of the perforated plate 10 inside. The silicone liner 3 therefore extends here respectively in the holes 15 in, so that the inner surfaces of the outlet openings are formed respectively by the silicone liner 3 35th The holes 15 in this case have an inner diameter D, and the outlet openings 35 of the silicone liner has an internal diameter d. The inner diameter d is sized smaller than the inner diameter D. Here, d is in each case dimensioned such that droplet formation is favored at the exit of the hot water from the outlet openings 35th Concretely, an inner diameter d of the outlet openings was selected to 35 of approximately 2.3 mm in the present embodiment. The radial thickness of the silicone liner 3 inside the holes 15, which corresponds to the difference between the inner diameters D and d, is approximately 0.6 - 0.8 mm. While the silicone liners 3 and 4 in the region of the side wall 31 of the inlet duct 32 and the inlet nozzle 33 has a constant thickness of approximately 1 - 2 mm long, 30 has the perforated plate of the silicone liner 4 a with respect to the direction of gravity varying thickness between about 1 - 2 mm and 4 - 5 mm. As can be clearly seen in the figure 2, the perforated plate of the recess 30 is thereby close to 34 formed on the thickest and diluted with increasing distance from the recess 34 so as to plane a, is slightly inclined surface with respect to the direction of gravity. This slight inclination of the upper surface of the perforated plate 30 causes the inflowing from the inlet duct 32 fro water are not left in the region close to the recess 34 on the perforated plate 30 and flows almost exclusively through the arrayed in this area outlet openings 35, but continues to flow through the perforated plate 30 and also opposite to the recess 34 remote outlet openings 35 reaches. The water is thus distributed better over the perforated plate 30 and exits from the various outlet openings 35 in uniform quantities.

On top of the perforated plate 30 flow elements 36 are formed, which upwardly extend into the distribution chamber 70 and in particular in Figures 4 and 5 are clearly visible. The flow elements 36 are here attached directly to the perforated plate thirtieth In other embodiments, but these may also be mounted for example at the cap. 5 The flow elements 36 serve to separate, and the water flow in the distribution chamber 70 to distribute the hot water perpendicular to the main direction of flow evenly over the perforated plate 30 so that it emerges in more uniform amounts of the various outlet openings 35th In this case, exactly three flow elements 36 are present. The flow members 36 in this case have 5 each substantially the shape of a forward slightly rounded wedge, whose tip points in the opposite direction to the main flow direction in the plan view of FIG. This wedge here has two legs, which each enclose an angle of approximately 70 °. One of the flow elements 36 is arranged in the immediate vicinity of the recess 34th With respect to a longitudinal axis of about 32 extends along the symmetry plane of the inlet duct 36 have the flow elements on a mirror-symmetrical arrangement. The two legs of each laterally spaced from the longitudinal axis of the intake passage 32 arranged flow elements 36 are formed of different lengths, wherein the closer arranged in the plane of symmetry each leg is much shorter. The height of the flow elements 36 corresponds approximately to that of the recess 34th

The distribution chamber 70 is closed off from above with a cap 5, which is removably insertable into the upper, defined by the side wall 11 opening of the housing. 1 The preferably one-piece and made from silicone sealing cover 5, which is particularly shown in the figure 7, a Verschliessfläche 50, to from this circumferentially upwardly extending side wall 51, and a support flange 52 which extends from the upper edge of the side wall 51 extends outwardly. Sealing ribs are formed on the radially outer side of the side wall 51, which allow a liquid tight connection with the side wall 31 of the silicone liner. 3 The support flange 52 serves to rest on the upper edge of the side wall 11 of the housing 1. When the cap is inserted into the housing 1 to 5, the Verschliessfläche 50 preferably abuts the flow elements 36th

The rear end of the intake passage 12 is liquid-tight in the present embodiment by means of a closure plug 6 closable. The closing plug 6 is removably insertable into the inlet channel 12 and preferably made integrally from silicone. As can be seen in Figure 9, it has a rectangular Verschliessfläche 60 with a circumferential side wall 61, from which a support flange 62 extending outwardly. The side wall 61 has on its outside to sealing ribs, which allow a connection to the inner surface of the inlet duct 32nd The support flange 62 serves to rest on the rear edge of the inlet channel 12 when the closing plug 6 is fully inserted into the inlet channel 12th

The invention is of course not limited to the above embodiment, and various modifications are possible. For example, the silicone liners 3 and 4 do not necessarily make all liquid-carrying inner surfaces of the distributor head. It is sufficient if, for example, a silicone liner is in particular in the region of the holes 15, ie within the holes 15 and / or on the inside of the perforated plate 10 is mounted. The liner must also not be made of silicone, but can also be of a different material which is more liquid-repellent compared to the case main body 1, may be prepared. The flow members 36, the sealing plug 6 and the cap 5 can be of any otherwise configured or even be completely omitted in each case. Also, the presence of an inlet channel is not mandatory. The inlet for the water in the manifold head could for example instead be disposed on an intake passage directly above the perforated plate. The housing cover 2 need not necessarily be present and could be formed integrally with the housing main part 1, for example, in particular from the beginning. A welding together of the housing cover to the housing main part would no longer be necessary in the production. A variety of other modifications are possible.
