Abstract

Faucet with warm button, characterized in that water can only flow through the hot water channel when the warm button is pressed.

Description

SUMMARY:

An additional release button for the hot water supply line prevents the pointless outflow of hot water when setting the temperature in single-lever lever mixers.

BACKGROUND OF THE INVENTION

For ecological and environmental reasons, water and energy should generally be saved.

• Denn in ihrer Grundstellung, d.h. den Steuerhebel waagrecht und mittig, lösen sie bei Beginn der Wasserentnahme stets eine Menge ungewollten Warmwassers aus, das sich mit dem Kaltwasser-Zulauf mischt und das man bis zum Erreichen der gewünschte Wassertemperatur ablaufen lässt.

One cause of losses, which are insignificant on a small scale but not insignificant when considering the total number of households, lies in the design of modern taps as single-lever lever mixers:

• Because in their basic position, ie with the control lever horizontal and in the middle, they always release a lot of unwanted hot water when water is drawn off, which mixes with the cold water supply and which is allowed to drain until the desired water temperature is reached.

OBJECT OF THE INVENTION

The object of the invention is therefore to provide a faucet with a warm button in order to dispense cold water without mixing it with hot water and only using it when necessary.

STATE OF THE ART

There are currently a few taps. These are the one from Hansgrohe under the brand name “Coolstart” and the one under the brand name “Quooker” with the push-turn operation. The “cool start” from Hansgrohe begins with cold water in the middle position and the water only becomes hot when turning. The “Quooker,” on the other hand, allows cold water to flow when a ring is pushed down once and hot water when the ring is pushed down the second time.

The DE 3 908 009 C2 describes a sanitary valve. A sanitary valve is proposed that has water inlets for hot and cold water. A control device determines the flow rate of water and ensures a constant minimum flow rate. In addition, the structure has an oral irrigator, which should be controlled in such a way that water is dispensed in small quantities at the appropriate temperature without having to wait for it to warm up.

The US 2019 0 106 868 A1 describes a faucet with a tap drain. A faucet includes two channels and a jet aerator. This has a jet breaker with a wall that has liquid passage openings. As a result, the two water channels are separated from each other and arranged according to the direction of flow by a coupling assembly. The structure separates hot and cold water and is intended to prevent mixing or wasting water.

SOLUTION

The inventive step here is that hot water cannot flow until the button is pressed. This means that the use of energy is more efficient because the water is not heated until the button is pressed.

By default, there is no hot water flow from the faucet; a button unlocks the inflow and ensures that the water is heated. If the water is turned off or set to cold, the button locks the hot water flow again and no longer delivers warm water until the button is pressed again.

If the water is turned off, connecting the water regulator to a separator allows it to snap back so that the basic setting of the faucet only outputs cold water.

DESCRIPTION BY DRAWING

• 1 shows a hand lever mixer tap (1) with the warm button (3) arranged on the body (2). This has a hot water setting (4) and cold water setting (5).
• 2 shows the cross section of the body (2) with a cold water pipe (6) and a hot water pipe (7) with a mixing body (8) in a basic position. The water from the two pipes (6,7) is separated from each other by a partition (9), so that only water from the cold water pipe (6) can flow through the mixing body (8) to the tap (1). The warm button (3) is used to set the setting so that only cold water can flow. The button (3) is connected to a spring (10) so that the mixing body (8) is pulled back into the position shown by the spring (10) when switching to hot water and switching off.
• 3 shows the cross section of the body (2) in the setting of the mixing body (8) for the hot water supply to the tap (1). Both lines (6,7) are open, which means water mixes according to the set temperature. The warm button (3) is set to a hot water flow and when the water flow is switched off, there is no longer any pressure on the mixing body (8) and it snaps into the original basic position by the spring (10), shown in 2 , back.

Claims (4)

Faucet with warm button, characterized in that water can only flow through the hot water channel when the warm button is pressed. Faucet with warm button Claim 1 , characterized in that the faucet is designed such that the warm button returns to the original setting, i.e. cold water setting, when the water is turned off. Faucet with warm button after at least one of the Claims 1 and 2 , characterized in that a separator separates the hot and cold water pipes from each other and that the faucet is designed in such a way that the separator only opens after pressing the hot water button. Faucet with warm button after at least one of the Claims 1 until 3 , characterized in that the faucet is designed in such a way that the warm button adjusts the mixing body and holds it with a spring, whereby when water flows through, the water pressure holds the spring and as soon as the water is turned off, the mixing body is pushed back in by the spring pressure the basic position locks.
