Description

Technical Field

[0001] The present invention relates to sanitary appliances. Such sanitary appliances are particularly used to supply liquid to washbasins, sinks, showers and / or bathtubs as required.

Background Art

[0002] The sanitary appliance may have a mixing valve for mixing cold water and hot water to form mixed water having a desired mixed water temperature. For this purpose, cold water can be supplied to the mixing valve via a cold water supply line and hot water can be supplied via a hot water supply line. The adjustment of the mixed water temperature can be performed via an operating element arranged in the appliance casing of the sanitary appliance. The discharge amount of the mixed water may be controllable by a valve. The valve is known, for example, from European Patent Application Publication No. 1903267. A disadvantage of known sanitary appliances is that a large construction space is required for the mixing valve and the operating element.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Therefore, the problem of the present invention is to at least partially solve the problems described with respect to the prior art, and in particular to provide a sanitary appliance that can be configured relatively compactly.

Means for Solving the Problems

[0004] This problem is solved by a sanitary appliance having the features described in the independent claims. Another advantageous configuration of the valve is described in the dependent claims. The features individually described in the dependent claims can be combined with each other in any technically meaningful form and can define another configuration of the present invention. Further, the features described in the claims are explicitly detailed and explained in the specification, and in that case another preferred configuration of the present invention is shown.

[0005] For this purpose, a sanitary appliance, at least - A mixing valve for mixing cold water and hot water to form mixed water having a desired mixed water temperature, wherein the mixed water temperature is adjustable by the rotation of a control disk of the mixing valve about a first rotation axis, -A first operating element, wherein the first operating element is rotatable about a second axis of rotation for operating a control disk, and the second axis of rotation does not extend parallel to the first axis of rotation. Sanitary utensils that possess these features contribute to this.

[0006] Sanitary fixtures serve to provide liquids, particularly water, to sinks, washbasins, showers, and / or bathtubs. The sanitary fixtures may preferably have a fixture casing made at least partially of (cast) metal, such as brass, and / or plastic. The fixture casing may have a spillway, which is fixedly or movably, particularly swivelably, and / or at least partially retractable, attached to the fixture casing. The fixture casing and / or spillway may have at least one spillway opening for liquid. Through this at least one spillway opening, liquid can be discharged, particularly around the sanitary fixture. The fixture casing can be mounted in particular to a support, such as a work plate, washbasin, sink, or washbasin. For this purpose, the support may have an assembly opening into which a fixture casing with an assembly section can be inserted, and / or the fixture casing can be mounted in this assembly opening by mounting elements, for example, in the form of nuts.

[0007] The sanitary fixture includes a mixing valve for mixing cold water and hot water to form mixed water having a desired mixed water temperature. The mixing valve is located in particular within the fixture casing or in the lower portion of the fixture casing. Cold water can be supplied to the mixing valve, particularly via a cold water conduit, and hot water can be supplied to the mixing valve, particularly via a hot water conduit. The cold water may have a cold water temperature of, in particular, a maximum of 25°C (Celsius), preferably 1°C to 25°C, and particularly preferably 5°C to 20°C. The hot water may have a hot water temperature of, in particular, a maximum of 90°C, preferably 25°C to 90°C, and particularly preferably 55°C to 65°C. The mixed water temperature is adjustable by rotation of a control disc of the mixing valve about a first axis of rotation. The first axis of rotation may extend, for example, parallel to and / or coaxial with the longitudinal axis of the fixture casing. The control disc may be formed, for example, in the form of a dynamic control disc, which is position-adjustable relative to a static control disc. Furthermore, the control disc may be formed in the form of a valve disc and / or may be made of ceramics at least partially. A static control disc is (fixed) located in the mixing valve casing of a mixing valve, in particular. Furthermore, the static control disc may have a cold water flow opening for cold water and / or a hot water flow opening for hot water. The cold water flow opening and / or hot water flow opening extend through the static control disc, in particular parallel to a first axis of rotation. The control disc is in particular mounted flat on the static control disc and / or is rotatable about a first axis of rotation such that the opening cross-sections of the cold water flow opening and / or the hot water flow opening of the static control disc are modifiable. For this purpose, the dynamic control disc may have at least one control opening, which extends through the control disc, in particular parallel to a first axis of rotation. By rotating the control disk on a static control disk, the mixing ratio of cold water and hot water in the mixing chamber of the mixing valve can be adjusted. The cold water and hot water can be supplied to the mixing valve, for example, through a first longitudinal end of the mixing valve, and the mixed water may be discharged from the mixing valve through a second longitudinal end of the mixing valve.The first longitudinal end and the second longitudinal end are located on opposite sides (axially) of the mixing valve. In other words, this means that the mixing valve is capable of axial flow, that is, parallel to the longitudinal axis of the equipment casing, for example.

[0008] Furthermore, the sanitary fixture has a first operating element, which is rotatable about a second axis of rotation for operating a control disc. The first operating element may be formed, for example, in the form of a lever, a rotary grip, or a rotary knob. Furthermore, the first operating element may be formed at least partially in a sleeve-like and / or tubular shape. The first operating element may be located, for example, in the fixture casing or on the outer surface of the fixture casing. Furthermore, the first operating element may be rotatable about a second axis of rotation, particularly by the user of the sanitary fixture. The second axis of rotation does not extend parallel to the first axis of rotation. In other words, the second axis of rotation may extend obliquely to the first axis of rotation. The first and second axes of rotation may intersect. Furthermore, the first axis of rotation and the second axis of rotation may extend at an angle of 30° to 150° relative to each other, preferably 70° to 110°, and most preferably (substantially) 90°. This enables a compact structure for sanitary fixtures.

[0009] A first operating element may be coupled to a control disk via a first transmission device. The first transmission device may be, for example, an angle transmission device.

[0010] The first transmission device may be a bevel gear transmission device. The bevel gear transmission device may include a first bevel gear and a second bevel gear. The first bevel gear may be coupled in particular to a first operating element. Furthermore, the second bevel gear may be coupled in particular to a control disk or an accompanying element of the control disk.

[0011] The first operating element may be coupled to the control disk via a Cardan joint, a flexible shaft, a Bowden cable, and / or bellows.

[0012] The first operating element may be coupled to the control disk via a second transmission device. The second transmission device may be formed, for example, as a transmission device preceding the first transmission device. Furthermore, the second transmission device may be positioned in the force transmission direction between the first operating element and the first transmission device. The transmission ratio of the second transmission device may be particularly greater than 1, thereby allowing the control disk to be operated particularly delicately and / or easily via the first operating element.

[0013] The sanitary fixture may have a valve for opening and closing a mixed water passage, the valve being operable by a second operating element. The mixed water passage is, in particular, a liquid conduit capable of supplying mixed water to, in particular, at least one outlet opening of the sanitary fixture. The valve may be located, in particular downstream of the mixing valve, when viewed in the direction of mixed water flow. Furthermore, the valve may be formed, for example, in the form of a diaphragm valve. For this purpose, the valve has a diaphragm, which may be made of, for example, a material that is at least partially elastic, such as rubber. The diaphragm may be formed in particular circular shape and / or attached to the valve casing. The diaphragm is attached to the valve casing, in particular in its radially outer region. In the closed position of the valve, the diaphragm is in contact with a (annular) valve seat. The valve seat is formed, in particular at the longitudinal end of the mixed water passage. Furthermore, the valve seat may extend around the spindle. In the closed position, the diaphragm closes the mixed water passage, thereby preventing the mixed water from flowing out through the mixed water passage or at least one outlet opening. To operate the valve, the diaphragm may be guided via a spindle coupled to a second operating element. This may particularly mean that the diaphragm is adjustable by the spindle parallel to a second axis of rotation. The diaphragm may be mounted in a diaphragm holder through which the spindle extends. The diaphragm holder is particularly a (rigid) plastic part. The diaphragm holder may be coupled to the diaphragm, for example, via a locking coupling. The second operating element may be formed in particular in the form of a push button. Furthermore, the second operating element may be rotatable (by the user of the valve) particularly about a second axis of rotation and / or adjustable parallel to the second axis of rotation. The spindle is particularly fixedly coupled to the second operating element, thereby allowing the spindle to move together with the second operating element. The spindle extends parallel to and / or coaxially with respect to the second axis of rotation.

[0014] The valve may be adjustable between an open position and a closed position by pressing a second operating element. For this purpose, the second operating element is coupled in particular to a locking device, which locks the second operating element in the open and / or closed positions. Such locking devices are known to those skilled in the art. By pressing the second operating element, the second operating element is adjustable together with the spindle, particularly into the valve casing, thereby guiding the valve diaphragm toward the valve seat, and the valve is positioned in the closed position. In this position, the second operating element is held by the locking device until it is pressed again. By pressing the second operating element, the second operating element is released by the locking device and moved away from the valve casing, particularly by spring force, until the valve or diaphragm is in the open position. In the open position, the diaphragm is lifted from the diaphragm seat, thereby allowing the mixed water to flow out through the mixed water passage or at least one outlet opening. The valve may be formed in the form of a so-called "push valve." Furthermore, the valve may be positioned above the mixing valve, especially when the sanitary fixture is attached to a support.

[0015] The volumetric flow rate of the mixed water may be adjustable by rotation of a second operating element. For this purpose, the second operating element and / or spindle are adjustable in position relative to the valve casing parallel to the second axis of rotation by rotation of the second operating element. The opening stroke of the valve or diaphragm may be adjustable by rotation of the second operating element, in particular. The opening stroke is, in particular, the working distance that the diaphragm is lifted from the valve seat in the valve open position, or the distance between the diaphragm and the valve seat in the valve open position. The working distance or distance is measured parallel to the second axis of rotation, in particular. The greater the adjustment of the working distance or distance by rotation of the second operating element, the greater the volumetric flow rate of the mixed water. The smaller the adjustment of the working distance or distance by rotation of the second operating element, the smaller the volumetric flow rate of the mixed water.

[0016] The second operating element may be rotatable about a second axis of rotation. In particular, the volumetric flow rate of the mixed water can be adjusted by rotating the second operating element about the second axis of rotation.

[0017] The first operating element and the second operating element may be arranged coaxially with respect to each other. Furthermore, the first operating element and the second operating element may be arranged coaxially on one side of the instrument casing. The second operating element may surround the first operating element, in particular, at least partially. Furthermore, the first operating element and the second operating element may be arranged coaxially with respect to each other on the opposite side of the instrument casing.

[0018] The present invention and related technologies will be described in detail below with reference to the drawings. It should be noted that the drawings show particularly preferred embodiments of the present invention, and the present invention is not limited to these illustrated embodiments. In the drawings, identical components are denoted by the same reference numerals. The drawings are illustrative and schematic. [Brief explanation of the drawing]

[0019] [Figure 1] This is a longitudinal cross-sectional view showing the first implementation variation of the sanitary fixture. [Figure 2] This is a longitudinal cross-sectional view showing a second implementation variation of the sanitary fixture. [Figure 3] This is a perspective cross-sectional view showing a portion of the second implementation variation of the sanitary fixture. [Modes for carrying out the invention]

[0020] Figure 1 shows a longitudinal section of a first implementation variation of sanitary fixture 1, where sanitary fixture 1 is shown only as a partial view. Sanitary fixture 1 has a fixture casing 13. This fixture casing 13 is mountable on a support (not shown) and extends along a longitudinal axis 14. A mixing valve 2 is located inside the fixture casing 13, and the mixing valve 2 has a mixing valve casing 15 equipped with a cold water supply section 16 and a hot water supply section 17. Cold water can be supplied to the cold water supply section 16 via a cold water pipeline 18, and hot water can be supplied via a hot water pipeline 19. A control disk 3 is located inside the mixing valve casing 15. This control disk 3 is formed as a dynamic control disk and is rotatable relative to a static control disk 20 about a first rotation axis 4 by a first operating element 5. In this implementation variation, the first rotation axis 4 of the control disk 3 extends coaxially with the longitudinal axis 14 of the fixture casing 13. The first operating element 5 is formed in the form of a sleeve and a rotating grip. Furthermore, the first operating element 5 is rotatable about a second rotation axis 6 that extends at an angle 23 of 90° with respect to the first rotation axis 4. Furthermore, the first operating element 5 is coupled to the control disk 3 via a first transmission device 7. The first transmission device 7 is formed in the form of a bevel gear transmission device and has a first bevel gear 24 and a second bevel gear 25. The first bevel gear 24 is coupled to the first operating element 5 so as not to rotate relative to it, and is rotatable about the second rotation axis 6 by the first operating element 5. Furthermore, the first bevel gear 24 engages with the second bevel gear 25, thereby allowing the second bevel gear 25 to rotate about the first rotation axis 4 by the first bevel gear 24. The second bevel gear 25 is coupled to the accompanying member 26 of the control disk 3, so that the rotational motion of the second bevel gear 25 leads to the rotational motion of the control disk 3 around the first rotation axis 4. The static control disk 20 is formed to be immobile relative to the mixing valve casing 15 and has a cold water passage opening for cold water, which is not shown in the drawing, and a hot water passage opening for hot water, which is also not shown in the drawing.By rotating the control disk 3 around the first rotation axis 4, the opening cross-sections of the cold water flow opening and the hot water flow opening of the static control disk 20 can be changed, thereby adjusting the mixing ratio of cold water and hot water in the mixing chamber 21 of the mixing valve 2. For this purpose, the control disk 3 has a control opening that is not visible in the drawing. By rotating the first operating element 5, the temperature of the mixed water formed in the mixing chamber 21 can be adjusted.

[0021] The mixed water can then be supplied via the liquid passage 22 to a valve 9 for opening and closing the mixed water passage 10. The valve 9 is formed in the form of a diaphragm valve and includes a diaphragm 28. The diaphragm 28 is attached to the valve casing 29 radially outward and, in the closed position 12 of the valve 9 as shown in the drawing, seats on an annular valve seat 30. The annular valve seat 30 is formed at one longitudinal end of the mixed water passage 10. The diaphragm 28 is attached to a diaphragm holder 31 through which a spindle 32 extends. The spindle 32 is coupled to a second operating element 11. The second operating element 11 is formed in the form of a rotatable push button, which is rotatable about a second axis of rotation 6 and is adjustable in position parallel to the second axis of rotation 6. In the closed position 12 of valve 9 as shown in the drawing, the second operating element 11 is in a pressed or adjusted position toward the valve casing 29, in which position the second operating element 11 is held by the locking device 33. This guides the diaphragm 28 to the valve seat 30 via the spindle 32, thereby closing the mixed water passage 10. By pressing the second operating element 11 again, the second operating element 11 is able to move parallel to the second rotation axis 6 toward the right or toward away from the valve casing 29, thereby lifting the diaphragm 28 away from the valve seat 30 by the spindle 32, so that valve 9 is in the open position. Thus, in the open position of valve 9, mixed water can flow from the liquid passage 22 into the mixed water passage 10 and then out to the surrounding area 27 of the sanitary fixture 1 through a mixed water outlet not shown in the drawing of the sanitary fixture 1.

[0022] The second operating element 11 is non-rotatably coupled to the pressing element 34, and within this pressing element 34, a threaded sleeve 35 is further non-rotatably arranged. The threaded sleeve 35 has an internal thread 36, and the internal thread 36 engages with the external thread 37 of the coupling sleeve 38. The coupling sleeve 38 is firmly coupled to the spindle 32. When the second operating element 11 rotates about the second axis of rotation 6, the pressing element 34 and the threaded sleeve 35 are rotated about the second axis of rotation 6 by the second operating element 11, whereby the coupling sleeve 38 is position-adjusted parallel to the second axis of rotation 6 together with the spindle 32. By adjusting the position of the spindle 32 parallel to the second axis of rotation 6, the opening stroke 39 of the valve 9 or the diaphragm 28 can be changed. Accordingly, by rotating the second operating element 11 about the second axis of rotation 6, the volume flow rate of the mixed water flowing out through the mixed water passage 10 can be adjusted. The first operating element 5 and the second operating element 11 are arranged together and coaxially with respect to each other on one side of the appliance casing 13.

[0023] Figure 2 shows a second embodiment of the sanitary appliance 1 in a longitudinal sectional view, and the sanitary appliance 1 is shown merely as a partial view as in FIG. 1. The second variation of the sanitary appliance 1 is different from the first variation of the sanitary appliance 1 in that the first operating element 5 and the second operating element 11 are arranged coaxially with respect to each other on opposite sides of the appliance casing 13. Further, the first operating element 5 is coupled to the control disk 3 of the mixing valve 2 via the first transmission 7 and the second transmission 8. The second transmission 8 is formed in the form of an epicyclic gear transmission or a planetary gear transmission. The first operating element 5 has a central gear 40, and this central gear 40 is rotatable about the second axis of rotation 6 together with the first operating element 5. The outer tooth row of the central gear 40 engages with the outer tooth row of the circulating gear 41, and the outer tooth row of the circulating gear 41 is held in a position-fixed manner in the casing component 43 by the shaft 42. The first bevel gear 24 of the first transmission 7 is formed in the form of an internal gear and has an inner tooth row, and the inner tooth row engages with the outer tooth row of the circulating gear 41. Thereby, the rotational movement of the first operating element 5 about the second axis of rotation 6 is transmitted via the central gear 40 and the circulating gear 41 to the first bevel gear 24 of the first transmission 7, whereby the control disk 3 is rotatable about the first axis of rotation 4. The transmission ratio of the second transmission 8 is greater than 1, whereby the control disk 3 can be easily operated via the first operating element 5.

[0024] Figure 3 shows a second embodiment of the sanitary appliance 1 in a perspective sectional view. In FIG. 3, it is possible to confirm, in particular, the circulating gear 4 of the second transmission 8 that engages with the central gear 40 and the first bevel gear 24.

[0025] According to the invention, the sanitary appliance can be configured particularly compactly.
