Description
Single hole basin fitting with a thermostatic mixing cartridge and a manifold
Description
The present invention relates to a single hole basin fitting for a wall mounted basin.
Such basin fittings are mounted to a horizontal surface of the wall mounted basin, wherein the cold and hot water are supplied through one single hole within the basin and through an opening at the bottom of the fitting body. The hot water is guided within the fitting in such a manner that it comes into direct contact with the internal surface of the fitting body before being mixed with the cold water, thereby increasing the temperature of the outer surface of the fitting body. If the user touches the heated surface of fitting body this might be at least unpleasant.
Accordingly, it is an object of the present invention to eliminate these disadvantages and in particular to provide a single hole basin fitting, which surface temperature is kept low during operation.
In accordance with the present invention, there is provided a single hole basin fitting, comprising a fitting body, in which a manifold and a thermostatic mixing cartridge are arranged, wherein the fitting body has one opening at its bottom through which cold and hot water can be supplied and a mixed water outlet aperture, wherein the manifold has a cold water inlet and a hot water inlet at its bottom and wherein the thermostatic mixing cartridge has a lateral hot water port, a lateral cold water port and a lateral mixed water port, wherein the manifold is formed and arranged in such a manner that a hot water chamber is formed through which hot water can be supplied from the hot water inlet of the manifold to the lateral hot water port of the thermostatic mixing cartridge and wherein the manifold and the fitting body are formed in such a manner that at least one cold water chamber is formed through which the cold water can be supplied from the cold water inlet of the manifold to the lateral cold water port of the thermostatic mixing cartridge, wherein at least one cold water chamber laterally surrounds the hot water chamber.
Accordingly, the invention suggests that the hot water chamber is formed in such a manner that the hot water does not impinge the preferably cast fitting body directly, but that the hot water chamber is at least partially delimited by the manifold. The manifold is preferably made of plastic. Alternatively, the manifold can be made of a less heat conducting material than the fitting body. The cold water chamber is preferably arranged between the hot water chamber and the inside of the fitting body. Additionally, the manifold can be arranged within the fitting body in a thermally insulating manner. By every means it is avoided that the fitting body is heated up extremely by the hot water.
The manifold is preferably formed in such a manner that the cold water received through the cold water inlet is guided to the outside of the manifold and into a cold water chamber that is delimited by the outside of the manifold and the inside of the fitting body.
The manifold can preferably be plugged into the fitting body through the opening at the bottom of the fitting body. Preferably thermally insulating elements are arranged between the manifold and the fitting body. In one embodiment the manifold is mounted by a snap fit connection to the fitting body. In particular, the manifold has tangs along its bottom for the snap fit connection, preferably molded in one piece to the manifold.
Each water port of the thermostatic mixing cartridge extends preferably around the whole circumference of the cartridge. A thermostatic expandable element can be arranged within the cartridge, which is surrounded by a mixing chamber of the cartridge. The expandable element regulates the position of at least one closing member for the cold water port and hot water port so that the temperature of the mixed water is kept constant. Such thermostatic mixing cartridges are already known.
The cold water inlet and the hot water inlet on the bottom of the manifold are formed in such a matter that they can receive elements that provide the water. For example, the inlets can comprise internal threads into which hoses or pipe connection elements for supplying the waters can be screwed. Alternatively, the inlets can be formed as plug openings, in which water providing elements can be plugged, eventually comprising snap elements for securing the water providing elements within the inlets.
In an embodiment a part of the thermostatic mixing cartridge comprising the lateral hot water port can be plugged into the manifold from the top, so that the hot water chamber is delimited by the inside of the manifold and by the plugged in part of the thermostatic mixing cartridge. This way the volume of the hot water chamber can be kept small and the hot water is directly provided to the hot water port of the thermostatic mixing cartridge. The hot water chamber within the manifold may be laterally completely surrounded by a lower cold water chamber.
In a further embodiment a lower cold water chamber is delimited by the manifold and the fitting body, wherein the fitting body has inwardly extending ribs which hold an upper part of the manifold and along which the cold water can flow from a lower cold water chamber to an upper cold water chamber, wherein the upper cold water chamber is delimited by the fitting body and the thermostatic mixing cartridge and wherein the lateral cold water port of the thermostatic mixing cartridge is arranged in the upper cold water chamber. Accordingly, the lower cold water chamber and the upper cold water chamber are interconnected by a free space between the ribs, which may be arranged circumferentially on the inside of the fitting body. The ribs may be formed by protrusions extending inwardly, wherein the ribs provide a stop for the manifold in the axial direction and which hold the manifold in a radial direction. A mixed water chamber delimited by the thermostatic mixing cartridge and the fitting body can be arranged above the cold water chambers, wherein the lateral mixed water port of the thermostatic mixing cartridge is arranged within the mixed water chamber. The mixed water chamber may extend to the mixed water outlet aperture of the fitting body.
In a further embodiment the fitting can be plugged with its opening at the bottom onto an inlet tail, which inlet tail can be preassembled to a basin and has a cold water nipple and a hot water nipple, wherein the hot water inlet and the cold water inlet of the manifold are formed as plug receiving openings for receiving the nipples of the inlet tail. Such a plug connection is in particular preferred, when the fitting shall be easily demountable after initial mounting.
The nipples preferably comprise a check valve which is opened by a pin extending axially within the inlets, so that the check valve is opened, when the fitting is plugged onto the inlet tail.
Preferably the inlet tail and the nipples as well as the fitting body are formed in such a manner, that in an assembled state air pockets are formed between the inlet tail and the fitting body and between the nipples and the fitting body. By such air pockets a heat transfer from the inlet tail or the nipples to the fitting body is reduced.
The invention and the technical field are described with respect to the enclosed drawing as way of an example.
Figure 1: shows a single hole basin fitting prior to mounting to an inlet tail,
Figure 2: shows a longitudinal cross section through the fitting in an assembled state and
Figure 3: shows a further longitudinal cross section.
Figure 1 shows an inlet tail 6 which is to be mounted onto a horizontal surface of a hand wash basin. The construction sided water pipes are connected to the inlet tail 16. The inlet tail 16 comprises a cold water nipple 17 and a hot water nipple 18 which extend upwards and through which the cold and hot water is provided, respectively.
Figure 1 further shows a single hole basin fitting with a fitting body 1. The fitting body 1 has one opening 4 at its bottom, with which the fitting body 1 can be plugged onto the inlet tail 16. The fitting body 1 further comprises a mixed water outlet aperture 5.
Figure 2 and 3 show sectional views, when the fitting body 1 is plugged onto the inlet tail 16, wherein figure 2 shows a cross sectional view through the cold water nipple 17 and the hot water nipple 18, while figure 3 shows a cross sectional view through the hot water nipple 18 only. A manifold 2 is arranged within the fitting body 1. Additionally a thermostatic mixing cartridge 3 is arranged within the fitting body 1. The thermostatic mixing cartridge 3 comprises in a known manner a lateral hot water port 8, a lateral cold water port 9 and a lateral mixed water port 10.
The manifold 2 comprises a cold water inlet 6 and a hot water inlet 7, into which the hot water nipple 18 and the cold water nipple 17 are plugged, respectively. A pin 21 is arranged within each inlet 6 and 7 of the manifold 2, which interacts with a check valve 20 arranged within the nipples 17, 18. In the assembled state the check valves 20 are opened, while in the disassembled state the check valves 20 are closed.
The inlet tail 16 and the nipples 17 and 18 are formed in such a manner that in the assemble state air pockets 19 are formed between the fitting body 1 and the nipples 17, 18 and between the fitting body 1 and the inlet tail 16.
The manifold 2 is formed in such a manner that the hot water provided through the hot water inlet 7 is guided into a hot water chamber 11, which is delimited by the inside of the manifold 2 and a plugged in part of the thermostatic mixing cartridge 3. This way the hot water is directly supplied from the hot water inlet 7 to the lateral hot water port 8 of the thermostatic mixing cartridge 3.
Furthermore, the manifold 2 is formed in such a manner that the cold water provided through the cold water inlet 6 is guided into a lower cold water chamber 12 surrounding the manifold 2.
An upper part of the manifold 2 is holded within the fitting body 1 by ribs 14, which provide a stop in the axial direction and which hold the manifold 2 radially.
The cold water can flow from the lower cold water chamber 12 through spaces between the ribs 14 into an upper cold water chamber 13, which is delimited by the fitting body 1 and the thermostatic mixing cartridge 3. The lateral cold water port 9 of the thermostatic mixing cartridge 3 is arranged in the upper cold water chamber 13.
Furthermore, a mixed water chamber 15 delimited by the fitting body 1 and the thermostatic mixing cartridge 3 is arranged above the upper cold water chamber 13 wherein the lateral mixed water port 10 of the thermostatic mixing cartridge 3 is arranged within the mixed water chamber 15. The mixed water chamber 15 extends to the mixed water outlet aperture 5 of the fitting body 1.
As the lower cold water chamber 12 surrounds the hot water chamber 11 delimited by the manifold 2 there is not direct heat transfer from the hot water to the fitting body 1. The heat transfer is further reduced as the manifold 2 is made of plastic. An additional reduction of heat transfer is also given by the air pockets 9 between the nipples 17, 18 and the inlet tail 16 on the one side and the fitting body 1 on the other side.
