Water temperature control device and method of operation thereof

Abstract

A water temperature control device and its operation method, the operation method includes the following steps: when the water outlet stops supplying water, use the control circuit to detect the mixing ratio; use the control circuit to obtain the current water temperature of the hot water tank, and according to the current water temperature, preset Set the hot water temperature and heating power to obtain the preset temperature recovery time, wherein the heating power is related to the rate of temperature rise of the hot water tank; use the control circuit to obtain the unit mixing ratio variation at least according to the mixing ratio, the preset mixing ratio and the preset temperature recovery time , and control the regulating valve to change the mixing ratio by unit mixing ratio variation, wherein the preset mixing ratio corresponds to the preset hot water temperature. The water temperature control device and its operation method in the present invention can provide warm water of a suitable temperature every time the user takes a bath, avoiding the user from being scalded by the water temperature being too high, so as to provide the user with a better user experience.

Description

technical field [0001] The invention relates to an operating method of a water temperature control device, in particular to an operating method of a water temperature control device applied to a water supply system. Background technique [0002] Today, the water supply system has become a popular household appliance. Generally speaking, when the hot water tank starts to provide hot water, cold water will be injected into the hot water tank and heated by a heater to maintain the water temperature of the hot water tank at a preset temperature. However, when the user starts to take a bath and consumes a large amount of hot water, and the water temperature of the hot water tank drops faster than the heating rate of the heater, the water temperature of the hot water tank will gradually decrease as the use time increases, and the temperature control of the water supply system The device will also automatically increase the proportion of hot water and reduce the proportion of cold...

Problems solved by technology

Therefore, when the water supply system is activated again, because the proportion of hot water provided by the temperature control device is too high, it cannot provide water with a suitable temperature. The control device provides excess hot water and increases, indirectly causing energy waste
