Instant-heating type constant-temperature water outlet device and control method and system thereof

Abstract

An instant-heating type constant-temperature water outlet device comprises a water tank with a water storage heating cavity, and a heating assembly arranged on the water tank, and the water tank is provided with a water inlet and a water outlet. The instant-heating type constant-temperature water outlet device further comprises a liquid level switch, a temperature control switch, a water outlet temperature sensor, a water inlet temperature sensor and a flowmeter. The liquid level switch, the temperature control switch and the water outlet temperature sensor stretch into the water tank to make contact with water. The water inlet temperature sensor and the flowmeter are connected with the water inlet. The heating assembly is provided with a fuse. The instant-heating type constant-temperature water outlet device can preheat water in the water tank to a target temperature before constant-temperature water is used, and when constant-temperature water is used, heating control is conducted according to the water inlet temperature, flow, input voltage and the target outlet water temperature which are all detected; it can be guaranteed that water is continuously output at the set constant temperature within three seconds, and the temperature deviation is within + / -1 DEG C; waiting is not needed, and the device is suitable for the fast pace of lives of modern people; and the instant-heating type constant-temperature water outlet device has the advantages of being capable of saving time, water and electricity, safe and environmentally friendly.
