Abstract

The invention discloses an air volume detecting and adjusting device which comprises a smoke outlet channel, an air pressure detecting device, a plain-end air pressure sampling nozzle and an inclined-end air pressure sampling nozzle, and the smoke outlet channel is provided with a vertical detecting section; the plain-end air pressure sampling nozzle is provided with a first air inlet end and a first air outlet end, the first air outlet end is connected with the air pressure detection device, the first air inlet end extends into the vertical detection section, and the first air inlet end is provided with a first air inlet; a bevel wind pressure sampling nozzle is provided with a second air inlet end and a second air outlet end, the second air outlet end is connected with the wind pressuredetection device, the second air inlet end extends into the vertical detection section, the second air inlet end is provided with a second air inlet, and the second air inlet and the first air inlet are formed in the same horizontal plane. The air volume detecting and adjusting device is adopted in the water heater, under the control of a constant air volume detecting and adjusting method, the influence of atmospheric pressure changes caused by different environments, altitudes and regions can be avoided, pressure changes in the smoke channel can be detected in real time, and the combustion working condition is adjusted according to the actual situation.

Description

technical field [0001] The invention relates to the technical field of gas appliances, in particular to an air volume detection and adjustment device, a water heater and a constant air volume detection and adjustment method. Background technique [0002] At present, most of the constant temperature gas water heaters on the market adopt the constant current control method or the wind pressure control method of the difference between the flue sampling wind pressure and the ambient pressure to adjust the fan speed. In an ideal state, when the air volume of the smoke collection channel is proportional to the speed, the constant current adjustment method can satisfy all the problems related to the wind speed, but considering the practical application of the fan in the burner, the air volume generated by the fan is affected by various Affected by various factors, such as combustion conditions, main cavity structure, environment, etc., as well as some special test items (such as bl...
