Description

The invention relates to a fitting according to the preamble of claim 1.

The invention further relates to a liquid dispensing system comprising such a fitting.

Although the present invention is generally applicable to any fittings, the present invention will be explained with reference to plumbing fittings.

Although the present invention is generally applicable to any liquid, the present invention will be explained with respect to water.

Sanitary fittings have become known in a variety of ways. Known sanitary fittings have, for example, a fitting body on which an outlet is rotatably mounted. To increase functionality, for example, from the EP 2 975 185 A1 a sanitary fitting has become known, the spout of which has a vertical and a horizontal section and has two separately arranged outlets in the horizontal section of the spout. The first outlet is designed in the form of a pull-out shower head and is used to dispense mixed water, the second outlet is used to dispense hot water and is permanently arranged in the spout.

Due to the large installation space required for the arrangement of the shower head and the jet regulator holder of the hot water spout, the hot water spout is arranged close to the vertical section of the spout. The disadvantage here is that the delivery of hot water is arranged disadvantageously close to the vertical section, which makes filling vessels with hot water significantly more difficult.

An object of the present invention is therefore to provide a fitting for dispensing liquids and a corresponding liquid dispensing system, which enable easier operation, high flexibility in terms of its handling and cost-effective implementation.

Another object of the present invention is to provide an alternative fitting and fluid dispensing system.

The term “processed liquid” is to be understood in the broadest sense and refers in particular in the claims, preferably in the description, to liquids, in particular water in the form of tap water from a water supplier or the like, which has additional properties and/or properties through a separate device. or its composition and/or method of preparation is changed. For example, treated water may have a high temperature, so-called hot water with a temperature of more than 80 degrees Celsius, a different degree of carbonation, a partially different composition or the like than the water originally provided by the water supplier. The term “processed liquid” in particular does not mean hot or cold water or mixed water, which is usually provided by a water supplier to a single-family home, apartment building or the like and whose temperature may be adjusted via a heater or the like.

The term "type of treatment" is to be understood in the broadest sense and refers, in particular in the claims, preferably in the description, not only to the basic type of treatment of a liquid, for example whether the water has been carbonated or not, but also to the degree Intensity or concentration of processing, for example the intensity of carbonization. Different types of processing mean, for example, different degrees of carbonation, for example “still”, “medium” or “classic”. Different types of preparation also mean different temperatures of hot water, water filtered to different degrees, different concentrations of flavor additives or aromatizations, different types of mineralization and different concentrations of the same type of mineralization or the like.

One of the advantages achieved with this is that it increases flexibility with regard to the arrangement of the spouts and the design of the spout. Another advantage is that the fitting is easy and cost-effective to install. Another advantage is that the safety and reliability of dispensing treated water for a user of the fitting is significantly increased.

Further features, advantages and further embodiments of the invention are described below or become apparent thereby.

According to an advantageous development, the second outlet part is designed in the form of an extendable shower head. The advantage of this is that the operability of the fitting for a user is further improved.

According to a further advantageous development, the horizontal distance between the liquid outlets when the second outlet part is fixed in the receiving part is at least 75% of the horizontal distance between a base body and the first liquid outlet. The advantage of this is that it enables particularly easy tapping of liquids and reliable and safe filling of vessels with the liquids.

According to a further advantageous development, the first liquid outlet is connected to a first line and the second liquid outlet is connected to a second line, with at least one of the two lines being made of flexible material and/or plastic. The advantage of this is that it is simple to manufacture and assemble to provide the tapping of two liquids via two outlets. If, for example, the first outlet part is a fixed outlet for functional or treated water, then, for example if the second outlet part is designed as a pull-out shower, scalding in the event of accidental incorrect operation can be prevented.

According to a further advantageous development, the second line is guided asymmetrically at least in the area of the receiving part. This enables simple assembly of the second outlet part including the second line together with the arrangement of the first liquid outlet.

According to a further advantageous development, the second line is guided through the receiving part in the upper region. The advantage of this is a particularly simple installation of the second liquid outlet in the lower region of the receiving part.

According to a further advantageous development, the receiving part and the first outlet part are designed such that the receiving part can be inserted into the first outlet part and releasably secured therein. The advantage of this is a particularly simple, detachable fixing of the first outlet part.

According to a further advantageous development, the receiving part can be fixed to the first outlet part by means of an element of the first liquid outlet, in particular by means of a jet former or jet regulator. This enables a cost-effective and simple fixation of the receiving part in the first outlet part, since separate fastening elements can be dispensed with.

According to a further advantageous development, the outlet essentially has a vertical and a horizontally extending area, with the receiving part and at least the second outlet part being arranged in the horizontally extending area. In addition to the advantage of a high visual appeal, the spout is easy to use.

According to a further advantageous development, the first outlet part is curved, in particular it is essentially L- or C-shaped. One of the advantages achieved with this is ease of manufacture and ease of use.

According to a further advantageous development, the outlet is at least partially cylindrical and a radius of curvature of the outlet is more than twice as large as a diameter of the outlet. In addition to a high visual appeal, this also provides sufficient installation space for the first and second lines of the two liquid outlets in the outlet.

According to a further advantageous development, the receiving part is at least partially made of plastic. This enables cost-effective production.

According to a further advantageous development, the outlet comprises an outer shell, which is in particular at least partially made of metal. Possible advantages of an outer shell made of metal are the high resistance to environmental influences and a high visual appearance of the outlet.

According to a further advantageous development, the first and/or the second line is at least partially arranged at a distance from the outer casing inside the outlet. This means that, for example, an insulating layer made of air or an insulating material can be arranged in the resulting gap in order to avoid burns when operating the spout, for example. Condensation formation at the outlet when dispensing cold liquids is also avoided.

According to a further advantageous development, the first line is designed for the flow of hot water with a temperature of more than 90 degrees Celsius, in particular more than 95 degrees Celsius. The advantage of this is that the first liquid outlet is also designed to dispense hot water, which increases the flexibility in providing different liquids and/or a liquid with different types of preparation.

Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures based on the drawings.

Preferred versions and embodiments of the invention are shown in the drawings and are explained in more detail in the following description, with the same reference numbers referring to the same or similar or functionally identical components or elements.

Figure 1 shows an exploded view of a fitting according to an embodiment of the present invention and Figure 2 a side and partially schematic view of the fitting Figure 1 .

They show in detail Figures 1 and 2 a sanitary fitting 1, for example for a sink in a kitchen. The sanitary fitting 1 includes an outlet 2 which is rotatably mounted about the vertical axis 50 in a base body 5. Corresponding operating elements 19 for providing mixed water or treated water can be arranged on the base body 5 via different water outlets 3a, 3b of the outlet 2. The outlet 2 is constructed in two parts and has a first essentially L-shaped outlet part 2a with vertical and horizontal areas 10, 11 and a second straight outlet part 2b in the horizontal area 11 of the outlet 2. Each outlet part 2a, 2b has a water outlet 3a , 3b on. Both outlet parts 2a, 2b are circular in cross section and hollow inside. In other words, an outer shell 13 is formed so that lines 6a, 6b can be routed in it. These lines 6a, 6b are flexible hoses and are each connected to one of the water outlets 3a, 3b. The radius of curvature 8 of the first outlet part 2a at the transition between the two areas 10, 11 is more than twice as large as the diameter 9 of the outer shell 13 of the outlet 2. The outer shell 13 can be made of metal, for example, the lines 6a, 6b, 60, 61, 62 can be made of polysiloxane, polytetrafluoroethylene or silicone and a receiving part 4 described below can be made of plastic.

Furthermore, the receiving part 4 is inserted into the first outlet part 2a at the end of the first outlet part 2a oriented towards the second outlet part 2b. The receiving part 4 is screwed into a corresponding receptacle in the jet regulator 7a Receiving part 4 is fixed in the first outlet part 2a via a corresponding opening 18 in the outer shell 13. One or more holding elements can also be arranged or used for this purpose. The second outlet part 2b also has a jet regulator 7b at its water outlet 3b. Furthermore, the second outlet part 2b is designed as a shower head and can be releasably secured to the first outlet part 2a by means of the receiving part 4. The line 6b is guided at least in the area of the receiving part 4 in the upper area C of the receiving part 4, in the lower area the water outlet 3a for the first outlet part 2a is arranged. The diameter of the outlet parts 2a, 2b can be dimensioned or designed such that the two lines 6a, 6b are arranged in the interior of at least the first outlet part 2a at a distance from the outer shell 13, for example spaced apart by an insulation layer or the like. The distance B between the base body 5 and the first water outlet 3a is greater than the distance A between the two water outlets 3a, 3b when the second outlet part 2b is releasably fixed to the first outlet part 2a by means of the receiving part 4. This enables a long second outlet part 2b, which improves its tangibility. The detachable arrangement can be carried out, for example, by partially inserting an element or section 21 of the second outlet part 2b into the receiving part 4 or the like.

In Figure 2 a water dispensing system 100 is shown, which on the one hand has two lines 60, 61 for providing cold and hot water, which can finally be dispensed as mixed water via a mixed water tap (not shown here) via the second water outlet 3b by actuating corresponding controls 19. The two lines 60, 61 are connected to a domestic water connection 120 for cold and hot water. The first water outlet 3a is connected to a water treatment module arrangement 101 via the line 6a connected to it and possibly a further line 62 - shown here only schematically. The water treatment module arrangement 101 can also be operated via corresponding operating elements 19 ', which can also be arranged on the base body 5, for example. The operating elements 19, 19' can be designed mechanically, electronically, pneumatically, hydraulically (or any combination thereof).
