Instant-type constant temperature and constant current campus warm water dispenser and its heating method

Abstract

The invention relates to an instant-type constant temperature and constant-current campus warm water dispenser and a heating method thereof. The water dispenser comprises a preheating water tank assembly provided with an inlet and a water outlet, an instant hot water boiling assembly and a second heat exchanger provided with mutual heat exchange. 1. The heat exchanger of the second water exchange channel, the first water exchange channel is provided with a low temperature water inlet and a first heat exchange outlet, the second water exchange channel is provided with a high temperature water inlet and a second heat exchange outlet; the low temperature water inlet passes through The first water inlet solenoid valve is connected with the main water inlet pipe, a branch of the first heat exchange outlet is communicated with the preheating water tank assembly through the second water inlet solenoid valve, and the other branch is communicated with the water inlet of the quick-heat boiling water assembly; One branch of the water outlet of the hot boiling water assembly is connected with the boiling water solenoid valve, the other branch is connected with the high temperature water inlet, and the second heat exchange outlet is communicated with the preheating water tank assembly; the quick heating water boiling assembly, the heat exchanger and the boiling water tap Both are below the maximum water level of the preheat tank assembly. It has the advantages of fast heating, stable water temperature and flow, and simple control.

Description

technical field [0001] The invention relates to a drinking water device, in particular to an instant constant temperature and constant current campus warm water dispenser and a heating method thereof; of course, it can also be applied to public places such as hospitals and governments, in addition to being used in campuses. Background technique [0002] The existing warm drinking water equipment is composed of a large heating water tank, a heat exchanger and a connecting pipeline. First, the cold water enters the water tank to boil, then enters the heat exchanger to cool down, and then presses out the faucet by the tap water pressure for use. , the first heating needs to wait for a long time, the heating cost is high, the service life will be affected by high temperature and high pressure, the water output speed of the faucet will be affected by the tap water pressure, resulting in unstable water output. When multiple faucets are opened at the same time, the water output is s...

[0002] Existing warm and hot drinking water equipment is composed of a larger heating tank, heat exchanger and connecting pipelines. First, cold water enters the tank and boils, then enters the exchanger to cool down, and then presses out the faucet for use by tap water pressure. , the first heating needs to wait for a long time, the cost of the heating tank is high, the service life will be affected by high temperature and high pressure, the water outlet speed of the faucet will be affected by the pressure of the tap water, resulting in unstable water outlet, when multiple faucets are opened at the same time, the water outlet is small and the temperature is low. The outlet temperature of the boiling water will be affected by the inlet temperature of the tap water. In summer, the temperature of the boiling water is too high, and the water stored in the tank will be reheated repeatedly after cooling down.
