Instant water dispenser intelligent temperature control system

Abstract

The invention discloses an instant heating water dispenser intelligent temperature control system which comprises a single-chip microcomputer, an inlet water temperature probe arranged in a water inlet pipe, an outlet water temperature probe arranged in a water outlet pipe, a heating disc for heating water pipes, an electromagnetic pump for controlling inlet water flow and a flow meter. The inlet water temperature probe, the outlet water temperature probe, the heating disc, the electromagnetic pump and the flow meter are electrically connected with the single-chip microcomputer. The system overcomes the defect in the existing instant heating water dispenser that only constant outlet water temperature can be guaranteed and constant heating power can not be guaranteed, or the constant heating power is guaranteed but the constant outlet water temperature can not be guaranteed, or the constant outlet water temperature and the heating power can not be guaranteed when the voltage is not stable. The intelligent temperature control system is widely applied to water dispensers.

Description

technical field [0001] The invention relates to a water temperature control system, in particular to an intelligent temperature control system for an instant water dispenser. Background technique [0002] At present, the temperature control system of the common instant water dispenser on the market generally achieves a constant outlet water temperature by controlling the power of the heating plate, but it does not control the flow of water, and can only work at a certain flow value. , thus resulting in different heating power when the inlet water temperature is heated to 95°C. For example, when the inlet water temperature is only 5°C in winter, the heating power is 2200W, but when the inlet water temperature reaches 30°C in summer, the heating power may be Only over 1000 watts. In this way, the power of the heating plate is not fully utilized, so that the water output in summer becomes smaller, and the instability of the power does not meet the 3C inspection standard. Or a...

Problems solved by technology

Or the constant outlet water temperature cannot be reached when the voltage is unstable

For example, it reaches 95°C at 220V, but it cannot guarantee the outlet water temperature of 95°C at 200V or 240V.

In addition, because the parameters of each heating plate and each water pump are different, and the voltage is unstable, the water temperature changes, etc., it is difficult for the instant water dispenser to achieve a constant water temperature and constant heating power.
