Problems solved by technology

However, due to the mechanical characteristics of the mixing valve, it may not be possible to control the mixing valve
[0009]At the same time, when the mixing valve in the electronically controlled hot water supply device fails, the mixing valve cannot be controlled normally
Therefore, when the heat of the burner is controlled based on the temperature before mixing, the hot water temperature set by the user may not be met

Abstract

The present invention provides an apparatus and method for supplying hot water. The apparatus for supplying hot water comprises: at least one processor; a heat exchanger connected to the at least one processor, and configured to receive tap water through a tap water inflow pipe, heat the supplied tap water by means of heat exchange to thereby generate hot water, and discharge the generated hot water through a hot water supply pipe; a burner configured to directly or indirectly provide heat required to generate the hot water; a mixing valve connected to the at least one processor and installed on a mixing pipe connecting the tap water inflow pipe and the hot water supply pipe, and configured to mix the tap water with the hot water discharged from the heat exchanger and flowing through the hot water supply pipe; and a memory connected to the at least one processor and configured to store instructions. Of the hot water flowing through the hot water supply pipe, when the hot water flowing upstream of a connection point with the mixing pipe is first hot water, and the hot water flowing downstream of the connection point is second hot water, the instructions, when executed, cause the processor to: obtain, on the basis of the temperature of the tap water and a required temperature of the second hot water, a reference temperature, which is a temperature of the first hot water that allows the mixing valve to maintain a predetermined opening rate; and control the burner such that the temperature of the first hot water discharged from the heat exchanger reaches the obtained reference temperature.

Description

technical field [0001] The present disclosure relates to an apparatus and method for supplying hot water, and more particularly, to a hot water supply apparatus and method for efficiently controlling a mixing valve. Background technique [0002] This application claims the benefit of Korean Patent Application No. 10-2018-0173563 and No. 10-2018-0173564 filed with the Korean Intellectual Property Office on December 31, 2018, the entire contents of which are incorporated by reference into this article. [0003] A hot water supply device is a device that heats direct water and supplies hot water at a temperature set by the user, and it is important that a hot water supply device supplies hot water for a short period of time and always provides a constant temperature when using hot water And hot water with no temperature difference. For this reason, a hot water supply device for supplying constant temperature hot water using a mixing valve is widely used. [0004] There are t...
