Abstract

The invention discloses a constant air amount control system for an instantaneous gas water heater. The constant air amount control system comprises a draught fan detection circuit, a single chip microcomputer circuit, a draught fan control circuit, a power circuit and a draught fan. The draught fan detection circuit is connected with the single chip microcomputer circuit. The single chip microcomputer circuit is connected with the draught fan control circuit. The draught fan control circuit is connected with the draught fan. The draught fan is connected with the draught fan detection circuit.The draught fan detection circuit is used for detecting the voltage, current and rotating speed of the draught fan. The single chip microcomputer circuit is used for receiving and calculating the draught fan voltage, current and rotating speed fed back by the draught fan detection circuit. The draught fan control circuit is used for controlling action of the draught fan. The power circuit is usedfor providing working voltages for all units. By means of the constant air amount control system for the instantaneous gas water heater, the draught fan voltage, current and rotating speed of the instantaneous gas water heater can be controlled, constant air amount control over the draught fan is realized ultimately, and the defects in the prior art are overcome.

Description

technical field [0001] The invention relates to the field of gas instant water heaters, and more particularly relates to a constant air volume control system for gas instant water heaters. Background technique [0002] The existing domestic fully automatic forced exhaust or intelligent constant temperature gas fast water heaters and wall-hung boilers that use AC power supply generally provide a fixed voltage for fan control. When the outside world changes, such as the input voltage of the fan changes or the flue is blocked Blockage, incomplete combustion or flameout at this time, may cause danger. How to achieve constant air volume control is the problem we are currently facing. Contents of the invention [0003] Aiming at the deficiencies of the above technologies, the present invention discloses a constant air volume control system for gas instant water heaters, which can realize constant air volume control of gas instant water heaters without being affected by factors ...
