Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single-lever mixing faucet and a kitchen sink, and more particularly to a single-lever mixing faucet suitable for installation in a kitchen sink and a kitchen sink equipped with the same.

[0002]

2. Description of the Related Art As shown in FIG. 2, a single-lever mixing faucet 1 adjusts a discharge water temperature by moving a single lever (lever handle) 3 provided on a top portion of a valve body 2 in the left-right direction. The single lever 3 is configured to be moved up and down to perform water discharge, switching of water stop, and water discharge amount adjustment.

The water discharge port 5 at the tip of the water discharge pipe 4 of this single lever mixed water faucet is directed downward, and water is discharged downward.

A normal single-lever mixing faucet is provided with only one water discharge pipe. In addition, the actual exploitation Sho 48-316
Japanese Patent No. 18 describes a two-way kitchen faucet provided with two water discharge pipes. The water discharge direction of this faucet is also downward.

[0005]

In the conventional single-lever mixing faucet 1 in which the water discharge direction is downward, the water discharge pipe 4 is lengthened to some extent so that water can be discharged near the center of the sink 6. It is necessary to
For a single lever mixed faucet 1 with a long
The water discharge pipe 4 tends to be an obstacle when washing inside. Further, especially when a large pot P or the like is put in or taken out of the sink 6, the water discharge pipe 4 becomes an obstacle. Further, even when the lever 3 is operated, the lever 3 and the water discharge pipe 4 often occupy a vertically overlapping position, so that the water discharge pipe 4 interferes with the hand H for operating the lever.

It is an object of the present invention to solve such a problem and to make the sink easy to use by reducing or eliminating the projection of the water discharge pipe into the sink.

[0007]

A single-lever mixing faucet of the present invention comprises a tubular valve body containing a hot and cold water mixing valve, and a single lever for adjusting water temperature and water amount provided on the top of the valve body. In a single-lever mixed faucet that extends from the side surface of the valve body and has a water discharge pipe provided with a water discharge port at the tip, the water discharge direction of the water discharge port is horizontal, diagonally upward or diagonally downward. It is characterized by that.

In such a single-lever mixing faucet, water is spouted from the spout pipe in a parabolic shape forward, and the spout pipe can be extremely short.

By providing a constant flow valve inside the water discharge pipe, the amount of water discharged from the water discharge port is limited. This prevents water from flying out of the sink.

In the present invention, a second water discharge pipe, which is different from the water discharge pipe, is extended from the side surface of the valve body, and the water discharge port at the tip of the second water discharge pipe is directed downward. You may comprise so that it may be located higher than the water outlet of the water pipe. With this configuration, water can be easily injected into the tall container from the second water discharge pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a kitchen single-lever mixing faucet 1 according to an embodiment installed on the back side of a sink 6.
It is a perspective view of A.

In this single-lever mixing faucet 1A, a single lever 8 is provided on the top of the valve body 7, and two water discharge pipes 9 and 10 are extended from the side surface.

The first water discharge pipe 9 comprises a base end portion 9a integral with the valve body 7 and a water discharge head 9b connected to the base end portion 9a by a ball joint so as to be swingable. The tip end surface of the water discharge head 9b is a water spray plate-shaped first water discharge port 9c for performing shower-like water discharge, but it may be one opening so as to discharge water in a bundle flow, and a slit. The shape of the water discharge port is arbitrary, for example, a water film is discharged as a circular opening.

A constant flow valve 11 is installed in the water discharge head 9b, and the discharge water W drops only into the sink 6 by limiting the water discharge speed from the water discharge port 9c to a predetermined value or less. .

The second water discharge pipe 10 is bent upward so that the middle thereof rises and the tip portion thereof is curved downward. A downward facing second water outlet 10a is provided at this tip portion, and the second water outlet 10a is the first water outlet 9c.
It is placed higher than.

On the side surface of the valve body 7, there is provided a switching lever 12 for selecting either the first water discharge port 9c or the second water discharge port 10a.

A mixing valve is installed in the valve body 7. This mixing valve is a well-known one having a lower fixed disk and an upper movable disk that are slidably overlapped with each other, and the movable disk is moved back and forth and left and right by a single lever 8 to adjust the discharge water temperature and The water discharge flow rate is adjusted (including stoppage of water and switching of water discharge).

A leg pipe for hot water and a leg pipe for water (both not shown) are projected from the bottom of the valve body 7, and a hot water inflow port and a water inflow port of the fixed disk are provided through the hot water flow path and the water flow path. Is in communication with. The mixed water outflow port of the fixed disk communicates with the switching valve via the mixed water flow path, one of the outflow flow paths separated from this switching valve communicates with the inside of the first water discharge pipe 9, and the other one of the second water discharge pipes. It communicates with the inside of 10. The switching lever 12 of the switching valve projects from the side surface of the valve body 7 as described above.

A part of the side surface of the valve body 7 is constituted by a cylindrical body 7a which is rotatable around the central axis of the valve body 7. The water discharge pipes 9 and 10 are connected to the cylindrical body 7a, whereby the water discharge pipes 9 and 10 are connected to the valve body 7.
It is rotatable in the horizontal direction around the axis of.

In the single-lever mixing faucet 1A and the kitchen sink constructed as described above, since the first water discharge pipe 9 is short, it does not interfere with the putting in and out of a pot or the like into the sink 6, and the lever 8 The first water discharge pipe 9 does not get in the way during the operation.

Further, since the water from the first spout 9c flies to the center of the sink 6 in a parabolic shape, dishes or the like can be washed near the center of the sink 6. This first water discharge pipe 9
Since the constant flow valve 11 is provided inside, the first spout 9
Water from c will not fly out of the sink 6.

By operating the switching lever 12 to discharge water from the second water discharge port 10a, water can be easily poured into a tall container.

[0023]

As described above, according to the single-lever mixed faucet and kitchen sink of the present invention, the water discharge pipe does not interfere when washing dishes or the like in the sink, and the water discharge pipe does not interfere when the lever is operated. It is extremely easy to use.

According to the single lever mixed faucet of the second aspect, water can be discharged only into the sink.

According to the single-lever mixing faucet of claim 3, water can be easily poured into a tall container.
