The invention discloses a four-way switching cold-hot mixed faucet, which comprises a four-way valve core (1), a valve casing (2) and a
handle (3), wherein an upper valve sheet and a lower valve sheet are arranged in the four-way valve core, a fan-shaped water chute is arranged in the upper valve sheet, and a cold washing water hole, a hot washing water hole, a
cold drinking water hole, a hot drinking water hole and a water outlet are formed in the lower valve sheet. During work, the
handle is pulled, a drive plate is driven through a drive key of the four-way valve core to drive the upper valve sheet to slide on the lower valve sheet; and through the switching communication or stoppage of the water chute arranged under the lower valve sheet and the cold washing water hole, the hot washing water hole, the
cold drinking water hole, the hot drinking water hole and the water outlet arranged on the lower valve sheet, a technical scheme that cold and hot washing water and cold and hot drinking water are controlled to flow out or stop through a water outlet
pipe of the valve casing from the water outlet is realized. The defect that two faucets are installed is avoided, the installation and use of users using washing and drinking water respectively are convenient, and the purposes of cost reducing,
interoperability and convenience in use are achieved.
