Abstract

The present invention discloses a gas-fired hot water device and a control method thereof. The gas-fired hot water device comprises: a first heat exchanger; a combustion device; a second heat exchanger with a first flow passage and a second flow passage, wherein the first flow passage is capable of communicating with the first heat exchanger; a third flow passage capable of communicating with thefirst heat exchanger; a first flow regulating device capable of distributing fluid flowing out of the first heat exchanger between the first flow passage and the third flow passage; a first water pumpcapable of driving fluid flowing through the first heat exchanger to flow into the first flow passage and/or the third flow passage; and a controller capable of controlling the first flow regulatingdevice and regulating the flow quantity of the first flow passage and the third flow passage when the thermal load required for the second flow passage is less than the minimum power of the combustiondevice. According to the device and the method of the present invention, hot water temperature can always be ensured to reach temperature set by a user by regulating the first flow regulating deviceand shunting the third flow passage when the required heat load is less than the minimum power of the gas-fired hot water device, thereby improving user experience.

Description

technical field [0001] The invention relates to the technical field of hot water engineering, in particular to a gas hot water device and a control method thereof. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] With the improvement of living standards, gas water heaters have become one of the requisite household appliances for people. A gas water heating device usually uses gas as fuel, and transfers energy to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water. Its specific forms include wall-hung boilers, gas water heaters, etc. [0004] The applicant found that: during the use of the existing gas-fired water heater, even if the gas-fired water heater operates at the lowest power, the temperature of the outlet water will still be too high and cannot be adjusted to the temperature set...
