Description

Faucet for sink {A faucet that can be easily installed in the sink}

The present invention relates to a faucet for a sink, and more particularly, to a faucet for a sink that can be assembled more simply and quickly than before, thereby securing assembly convenience, and easy reinstallation and maintenance to reduce costs. .

In general, a faucet is installed in a sink or bathtub and selectively discharges hot or cold water or mixes and discharges it.

In this faucet, a conversion cartridge capable of selectively or mixedly discharging cold and hot water according to the operation of a lever is provided inside the one-hole faucet installed in the sink, and the conversion cartridge and one side of the connector are connected by a fastening method. An existing structure in which a pipe is coupled and connected to an end of the connecting pipe by a fastening method is proposed.

However, existing faucet fittings have a narrow inside of the one-hole faucet, so it was difficult to screw one side of the connector to the conversion cartridge. The connector itself was twisted or twisted and easily damaged, adding to the inconvenience of replacing and installing single-hole faucets.

In addition, in assembling by fastening one side of the connector to the conversion cartridge inside the one-hole faucet, when the working space is narrow and the fastening part is damaged due to excessive screw fastening, the hassle of replacing the conversion cartridge and the increase in work time and There was a problem with increasing costs.

Therefore, in order to fasten and assemble the connector to the conversion cartridge, the operator can apply adhesive to the fastening part of the connector to increase the coupling, but maintenance There was a problem of excessive cost.

On the other hand, Patent Document 2 is a faucet fitting in which connection pipes are connected to conversion cartridges having fitting holes for cold, hot water and mixed water, respectively, and discharge cold, hot water or mixed water supplied to the conversion cartridge through the discharge port according to the operation of the control lever. In the configuration, a receiving space having a locking jaw formed at the inner end of the fitting hole is provided, a female coupler is assembled in the receiving space, and a male coupler is inserted into the female coupler and coupled with one touch to the connecting pipe, and the cartridge of the faucet is configured. A faucet fitting with ease of assembly and ease of use is proposed by providing a one-touch fastening member to the connecting pipe so that it can be assembled more simply and quickly.

However, in Patent Document 2, it is very difficult to work to reassemble the connector for maintenance because the female coupler and the male coupler must be directly connected in a narrow accommodation space, similar to the existing faucet fitting.

That is, the conversion cartridge with the female coupler is inserted into the front, and the connector with the male coupler is inserted from the bottom of the sink to be fastened with one touch in the accommodation space, so the operator puts his or her hand into the accommodation space or uses a separate tool to fasten. The inconvenience of having to do is the same as before, and in order to reinstall it, there is a problem of poor workability because it is possible to separate all the faucet fittings from the sink.
