Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier faucet which can be used for various purposes.

[0002]

2. Description of the Related Art In a so-called water purifier faucet, a water purifier is usually connected in the middle of a water supply passage from a water supply source (tap) to a water discharge port. Then, the raw water supplied from the water supply source is passed through a water purifier, and unnecessary components and harmful components (calcium, trihalomethane, etc.) in the raw water are passed through a water purifier. Is removed.

[0003]

In recent years, various functions have been required for faucets, and this faucet faucet is no exception. That is, instead of having the water purifier faucet perform only the discharge of raw water or the like, or the discharge of purified water, for example,
There is a demand that a water purifier faucet can be used for more purposes by enabling connection with peripheral devices such as a dishwasher, a dishwasher, an alkaline ionized water producing device, and a shower head.

[0004] However, the conventional water purifier faucet does not have such a structure in consideration of the connection of the peripheral equipment, and thus cannot satisfy such a demand.

The present invention has been made in view of the above-mentioned viewpoints, and has as its object to provide a water purifier faucet which can be used for various purposes.

[0006]

A water purifier faucet according to claim 1 is a water purifier faucet in which a water purifier is connected to a water supply flow path, the water purifier being branched from the water supply flow path, and the periphery of the water purifier faucet. And a branch connection port that is connected to a peripheral device installed in the device.

According to the present invention, a peripheral device can be connected to the branch connection port, so that a water purifier faucet can be used for various purposes. Also, in order to enable versatile use with a single water purifier faucet, compared to the case where a conventional water purifier faucet is used in combination with another faucet for supplying water to peripheral equipment, Not only can the installation space for the faucet be reduced, but also the construction cost of the faucet can be reduced.

Furthermore, the present invention uses a single water purifier faucet for multiple purposes even when the space for installing the faucet is narrow (for example, a sink in a one-room apartment) and it is difficult to use a plurality of faucets together. It has great significance in being able to do so.

Here, the "branch connection port" of the present invention is a portion to which a pipe or the like interposed between a water purifier faucet and peripheral equipment is connected. It is provided on the bottom side or the top side or the like. The type of the “peripheral device” is not particularly limited, and examples thereof include a dishwasher, a dishwasher, an alkaline ionized water producing device, a shower head, and a faucet other than the faucet faucet. In this peripheral device, the raw water arriving from the water supply channel is never returned to the water purifier faucet.

Various types of water purifier faucet can be selected. For example, (a) the water purifier is located on the primary side (upstream side) of a water stop valve or the like (hereinafter referred to as "type 1"). (B) The water purifier is located on the secondary side (downstream side) such as a water stop valve (hereinafter, referred to as
"Type 2". ).

[0011] Further, even if the water purifier and the faucet main body are of an integrated type (hereinafter referred to as "integrated type"),
Type where both are separate (hereinafter referred to as "separate type"
That. ).

According to a second aspect of the present invention, in the water purifier faucet of the first aspect, the water supply flow passage in the faucet main body is branched into a water purifier flow passage and a peripheral device flow passage, and the water purifier flow passage or the periphery thereof. A switching valve for selectively opening and simultaneously closing the device flow path is provided.

According to the present invention, since the switching valve for selectively opening the flow path for the water purifier or the flow path for the peripheral device is disposed in the main body of the water faucet, the valve between the water purifier faucet and the peripheral device is disposed. There is no need to retrofit a valve device (water stop valve, etc.) to the piping etc. Also, when this piping etc. is exposed as an external appearance,
Since there is no valve device (water stop valve or the like) in the middle of the piping or the like, the periphery of the water purifier faucet becomes clean.

The switching valve system according to the second aspect of the present invention can be variously selected. For example, "a sliding disk system constituted by using a fixed disk and a movable disk which slide and open and close the flow path" And a lift-type temporary water stop type switching valve that switches a flow path and adjusts a flow rate by moving a valve body to and from a pair of opposed valve ports.
Since the former switching valve can be easily reduced in size, it is effective when it is desired to reduce the size of the faucet body. Since the latter switching valve is generally inexpensive, it is effective in further reducing the cost of the water purifier faucet.
