FAUCET FOR CASCADE FLOW

DESCRIPTION

Subject of the Invention The subject of the invention relates to a special valve cover developed for the purpose of eliminating the problems encountered in the fixtures with natural flow, especially in the fixtures that provide cascade type of flow, such as the failure of the water to flow uniformly during the exit thereof from the body, the splash of the water during its free flow from the outlet of the fixture and the damage caused by the water on the body wall of the fixture due to the impact of the water on said wall during its flow inside the body, and to a fixture comprising this cover.

State of the Art

In the fixtures, e.g. the cascade type fixtures, which are used according to the state of the art and which provide the free flow, the water flows by advancing to the outlet of the fixture through the opening in the body. The mains water entering the fixture flows into the body opening from the side of the valve cover, advances through the body opening and reaches the user via the outlet of the fixture. Since the water flowing into the body opening may not be guided during said flow of water, an irregular flow develops and the problems such as the splash of water also occur simultaneously. Moreover, the water damages the body wall of the fixture depending on the flow rate. The flow of water may be taken under control with the aid of the flow throttling component used according to the state of the art. However, the use of a flow throttling component increases the costs as it necessitates the use of an additional part.

Owing to the special valve cover developed within the scope of the invention, the uniform flow is achieved inside the body by directing the flow water in the fixture and the mentioned problems are eliminated. Object of the Invention

The object of the invention is to develop a special valve cover, by means of which the problems encountered in the fixtures with natural flow, especially in the fixtures that provide cascade type of flow, such as the damage caused by the water on the body wall of the fixture during its flow inside the body, the failure of the water to flow uniformly during its free flow from the outlet of the fixture and the splash of the water during its free flow from the outlet of the fixture are eliminated without using an extra part and by means of which the flow of water may be taken under control, as well as to develop a fixture comprising such cover.

The subject of the invention relates to a special valve cover developed for the purpose of eliminating the problems encountered in the fixtures with natural flow, especially in the fixtures that provide cascade type of flow, such as the failure of the water to flow uniformly during its exit from the body, the splash of the water during its free flow from the outlet of the fixture and the damage caused by the water on the body wall of the fixture due to the impact of the water on said wall during its flow inside the body, and to a fixture comprising such cover.

With the valve cover developed within the scope of the invention, the flow of water inside the fixture body and the flow of water to the outlet may be kept under control without using a flow throttling component in a fixture with natural flow, especially in a fixture that provides the cascade type of flow. By means of the system developed, the problems that could occur in connection with the flow rate of water are also prevented without the need for any extra part. The water reaches the user without damaging the fixture body wall (21) and without causing any problem of splash. The valve cover developed within the scope of the invention and the fixture comprising said valve cover can be seen in detail in the figures. A protrusion-shaped surface (14) is positioned on the valve cover (3) developed within the scope of the invention. Said protrusion-shaped surface (14) is formed on the valve cover (3) by surrounding said valve cover (3) in the form of a circle (Figure 4). Owing to this protruding surface, the water is directed during its flow through the fixture body and in this manner, the water is enabled to flow uniformly towards the outlet. It is possible for said protrusion-shaped surface (14) to have different shapes and forms that would enable the water, which advances from the valve to the body opening and from the body opening to the outlet, to be directed during its exit from the valve. The component parts of the fixture developed within the scope of the invention can be seen in Figure 4. The fixture comprises at least one fixture outer body (1), at least one valve (2), at least one valve cover (3), at least one inner body (5), sealing members (4a, 4b, 4c, 4d), at least one mixing shaft (8), at least one adapter piece (9), at least one mixing arm (10), fixing members (7a, 7b, 7c, 7d) and at least one sensor (11) to enable the water flow to be triggered by the user.

The valve (2) is fixed to the toothed section inside the inner body (5) via the toothed section (2a) on said valve. The section (5b) where the valve (2) is fixed to the toothed section on the inner surface of the inner body (5) can be seen in Figures 1, 2, 3 and 6. The valve cover (3) is fixed to the toothed section (5a) on the outer surface of the inner body with the help of the toothed section on the inner surface thereof. The valve (2) is positioned into the valve cover (3) that surrounds said valve. At least one sealing member (4a) is positioned between the inner body (5) and the valve cover (3). The adjustment of the desired temperature for the water to flow through the fixture is possible with the help of the mixing arm (10). The mixing arm (10) is fixed on the mixing shaft (8) with the help of the adapter piece (9). At least one sealing member (4d) is positioned between the mixing arm (10) and the adapter piece (9). The mixing shaft (8) is fixed into the inner body (5) with the help of at least one fixing member (7c). At least one sealing member (4c) is positioned between the mixing shaft (8) and the adapter piece (9) and the mixing shaft (8) and the adapter piece (9) are fixed together with the help of at least one fixing member (7d). At least one sealing member (4e) is positioned on the end of the mixing shaft (8) where the connection is made with the inner body (5). The sensor (11) is fixed to the inner body (5) by means of at least one fixing member (7b). The inner body (5) is fixed to the fixture body (1) with the help of at least one fixing member (7a). At least one sealing member (4b) is positioned between the inner body (5) and the fixture outer body (1).

Said sealing members (4a, 4b, 4c, 4d, 4e) are each preferably an o-ring. The sensor (11) is fixed to the valve (2) via the upper piece (12) thereof and the electrical connection is provided via the lower piece (13) thereof. In order to prevent the fixing member (7c), which fixes the mixing shaft (8) to the inner body (5), from damaging the sensor (11), at least one protecting piece (6) is positioned between the sensor (11) and the fixing member (7c).

Of said fixing members, the fixing member (7b) that fixes the sensor (11) to the inner body (5) is a stay bolt, while the other fixing members (7a, 7c, 7d) are screws.

Upon the user triggering the water flow with the help of the sensor (11), the hot water and/or cold water enters the fixture via the hot water inlet (15) and/or cold water inlet (16). The hot and/or cold water entering through this section reaches the mixing shaft (8) and the mixed water formed here by a mixture of the hot and cold water or only the hot water or cold water reaches the valve (2). The mixed water or only the hot water or cold water leading from the mixing shaft (8) enters the valve (2) via the hot and/or cold water valve inlet (20, 19). In case the user desires to use only the cold water, the water entering via the cold water inlet (16) reaches the mixing shaft (8) and from here it reaches the valve (2) via the hot water valve inlet (20) or cold water valve inlet (19). In case the user prefers only the hot water, the water entering via the hot water inlet (15) passes through the mixing shaft (8) and reaches the valve (2) via the hot water valve inlet (20) or via the cold water valve inlet (19). In case the user prefers to use the warm water, both the hot water and cold water enters the fixture via the hot water inlet (15) and the cold water inlet (16) and the mixed water, which is formed by way of mixing the waters in the mixing shaft (8) where they reach in a similar manner, enters the valve (2) via the hot and/or cold water valve inlet (20, 19). The water, which starts to fill in the body opening (18) when the valve cover (3) is opened, advances from this section to the water outlet (17). The water exiting the valve (2) hits the protrusion-shaped surface (14) on the valve cover (3) as it passes into the body opening (18) and the flow of water is controlled by way of directing performed by the protrusion-shaped surface. In this way, the water advances to the fixture's water outlet (17) with a uniform flow. On the contrary, in the fixtures used according to the state of the art, the splashes form when the water emerging from the valve (2) reaches the user via the outlet (17) as a result of the free flow of the water during its passage into the body opening without being directed. Owing to the valve cover (3) and the protrusion-shaped surface (14) on the valve cover developed within the scope of the invention, the flow direction of the water is kept under control and the problem of splash encountered when the water reaches the user is prevented with the more uniform flow of water.
