DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a sink incorporating a water purifier.

[0002]

2. Description of the Related Art In recent years, water sources have been remarkably polluted by pollution and the like, and the odor and dirt of tap water have become severe, which has become a social problem. In response to such water source pollution, a large amount of chlorine or the like is supplied to tap water, but the water quality is deteriorating year by year, and the water becomes unpleasant with odor. In view of this situation, water purifiers that can be used at home have recently become widespread.

[0003] The above-mentioned water purifiers include (1) a type in which a water purifier body is directly attached to a tip of a faucet (for example, see
60-153912), (2) A branch pipe with a switching valve is provided at the tip of the faucet, and tap water is sent from the branch pipe through a flexible pipe to the water purifier once, purified by the water purifier, and then re-formed. Type that returns to the tip (for example, 54-1574
No. 74), (3) There is a type in which a water supply pipe connected from a water pipe to a water purifier is branched, purified water introduced from the water supply pipe is purified by the water purifier, and purified water is discharged from a dedicated faucet.

[0004] In the case of the type (2) of the water purifier, when the water purifier body is designed to be movable, the position for installing the water purifier body can be selected to some extent. It is common to be installed on the upper grade.
Considering that the water purifier of type (3) introduces purification water directly from the water pipe, it is usually necessary to install the water purifier body in a storage space for storing pots etc. below the sink. General.

[0005]

However, among the above-mentioned conventional water purifiers, the water purifier of the type (1) has an advantage that the water purifier main body can be easily installed without performing water pipe work. Since the water purifier body is directly attached to the tip of the faucet, the size of the water purifier must be reduced. As a result, the water purification mechanism is also downsized. Inferior,
If a water purifier with a large size is attached to the tip of the faucet, it is inconvenient to use less space for the sink. Above all, there is a possibility that foreign matters are attached to the tip of the faucet and the beauty of the sink itself is impaired.

[0006] In addition, the type (2) has only a branch pipe with a switching valve at the tip of the water supply, so it does not have the drawbacks of the type (1) water purifier, and the piping is made flexible. Since the water purifier body is movable,
It has the advantage that the installation position can be selected to some extent if it is within the range of the length of the pipe, but considering the situation of a normal sink, it is generally considered that it is generally placed on the top plate of the sink, It is not preferable to install an additional water purifier in a narrow sink space because the work space is reduced. And, like the type of (1), installing a water purifier on the sink in a stripped-down manner impairs the beauty of the sink.

Further, the type (3) has an advantage that the beauty of the sink is not impaired, but it is necessary to provide a water purifier in a storage space for storing the pot below the sink. Not only does the storage space for large kitchen utensils decrease, but it is difficult to install a water purification cartridge, which is essential in household water purifiers.

In view of the above-mentioned drawbacks of the conventional water purifier, the present invention does not reduce the storage space of the sink and the working space on and around the sink, allows easy installation of the water purification cartridge, and improves the beauty of the sink itself. The purpose is to provide a built-in sink that is not damaged.
