Abstract

The invention discloses a gas heating device and a control method thereof. The control method includes the step: regulating the gas intake flow of a gas inlet channel according to pressure in a smokeexhaust channel when the gas heating device is in a working state, so that complete combustion of gas can be ensured. When the smoke exhaust channel is blocked to a certain degree, the pressure in thesmoke exhaust channel continues to be reduced to the lowest pressure value, the device is turned off, false alarm of the device can be effectively avoided, and use comfort of a user is improved.

Description

technical field [0001] The invention relates to the technical field of gas equipment, in particular to a gas heating equipment and a control method thereof. Background technique [0002] Gas heating equipment such as gas water heaters and gas heating water heaters are more and more widely used in people's lives due to their advantages of convenient heating and energy saving. The gas intake flow rate of existing equipment is only adjusted according to the required heating temperature. In this way, when the exhaust pipe of the gas heating equipment is blocked, the combustion of the gas will be incomplete, and harmful gases will be easily discharged. [0003] In addition, in order to ensure the safety of the gas heating equipment, when the exhaust pipe of the gas heating equipment is blocked, it is necessary to control the shutdown of the gas heating equipment. The existing control method is to use a wind pressure switch or a wind pressure sensor to detect the pressure change ...
