DE1963371A1 - Single-lever mixer tap with self-closing device - Google Patents

Description

Description Single-lever mixer taps have been known for some time as sanitary fittings whose regulation via a rotary knob or the like, i.e.

only done with one hand.

The applicant is a licensee of the invention of a self-closing valve, those through DP Er. 1 199 564 and verschO Ausl. Is protected by patents. With the violent ones However, this invention is no longer up-to-date with lifestyle habits. Therefore, the ROTOX-Ges.

embarked on a completely new path. It became a self-closing valve Developed as a single lever mixer.

All single-lever mixers known to date are easy to use the one-hand control, but are due to the fact that the water outflow at the same time the regulation is quite susceptible to repair and complicated, i.e. expensive to set up. Farther are especially with these mixers due to useless running water (only when washing your hands 45-5o% of the water consumption is lost unused during the cleaning process), the usage costs are particularly high, since there are still the heating costs for the hot water to be added.

Through the invention described below, the ROTOX-Ges.

eliminates this factor. A real self-closing valve was developed with a control device hot / warm / cold.

Furthermore, by changing the patent mentioned at the beginning, the Possibility created in the self-closing valve to build a permanent flow device.

Figure 1 shows the valve body in section, Figure 2 shows the same body with internal parts.

A spindle b leads through the hole a to the pinion a. The on Rotary movement produced by knob d is from the pinion c to the gear wheel e and from there brought about the axis f on a, for example, slotted piston g.

The warm and cold water supplied through the two tubes h and i Arrives through the slotted piston in a controlled manner, i.e. metered, depending on the position of the slits into the free space in front of the membrane disc 1.

This completes the process of mixing the water.

To avoid a compensation of cold and hot water ii idle state, for example, a closing piston m closes the tubes h and i by means of a compression spring n so that no water can flow over them.

The water is drawn off via the actuation sensor o in the vaderen Fitting part. (DP Kr. 1 199 564) The aforementioned patent is incomplete in this respect, because there is no possibility of permanent withdrawal. Due to the constructive change of the sensor head, this continuous operation is now guaranteed.

For this purpose, the sensor o has a locking shoulder in the upper part. Same is in the fourfold slotted cylinder p of the self-closing device for desired continuous operation pushed. By the necessity of a conscious act, namely that of pushing up it is guaranteed that no unwanted continuous flow can occur. Should this continuous flow are finished, it is sufficient to press lightly against the feeler. This is also at the same time the valve is ready for operation again as a self-closing valve.

Claims (4)

Protection claims One-hand mixer tap with self-closing device characterized that this self-closing valve designed by a mixing device for one-hand mixer will. 2. Mixing device according to claim 1, characterized in that this Mixing device the rotary movement generated on the rotary knob via a spindle and a Gear ratio transmits to a slotted piston. Slotted piston according to claim 2, characterized in that äe after Position these slots as a function of the supply of hot and cold water is regulated by each other, with a closing piston in the idle state the water supply closes to avoid a compensation of cold and hot water. 4. One-hand mixer tap with self-closing device according to claim 3 characterized in that the existing opening sensor for the water outlet The head is milled, which optionally enables a continuous flow.
