Embodiment 1
[0040]The first embodiment of the present invention provides a noise adaptive control method of a water heater, such asfigure 1 with2As shown, the water heater fire row is set with multiple stages, and the method includes the following steps:
[0041]S1. Detect the noise value of the current section of the water heater fire row, and judge whether the wind pressure of the water heater duct is stable and normal according to the noise value; if yes, keep the current fire row section load, if not, go to step S2;
[0042]S2, increase the segment of the water heater fire row, and keep the total load unchanged, so that the load of each burning water heater fire row is reduced, and then repeat step S1;
[0043]Through the above method, the noise value of the water heater is detected and matched with the load of the water heater fire exhaust. It is judged whether the air pressure of the water heater is stable and normal, and whether the oxygen supply is sufficient and the combustion is stable. If the...
Embodiment 2
[0067]The second embodiment of the present invention provides a water heater, such asimage 3As shown, it includes a water heater body 1, a noise detection unit 2 and a controller. The controller is arranged on the water heater body 1, and the noise detection unit 2 is arranged on the side of the combustion chamber 11 of the water heater body 1. The controller is based on the noise detection unit 2 The detection value controls the working condition of the fire exhaust in the combustion chamber 11.
[0068]With the above structure, the noise detection unit 2 detects the noise during the combustion of the fire exhaust, and the controller controls the working condition of the fire exhaust according to the self-adaptive control method for noise of the water heater provided in the first embodiment. The water heater can burn stably.
[0069]This embodiment also includes a wind pressure switch 3, which is installed on the water heater body 1, and the controller controls the operation of the combu...

Abstract
The invention discloses a water heater noise self-adaptive control method and a water heater. The method comprises the steps of S1, detecting a noise value of a current-segment water heater fire grate, and judging whether the air pressure of a water heater air duct is stable and normal or not according to the noise value; if yes, keeping the current fire grate segment load, and if not, entering the step S2; and S2, increasing the segments of the fire grate of the water heater, keeping the total load unchanged, enabling the load of each burning fire grate of the water heater to be reduced, andthen repeating the step S1. The water heater comprises a water heater body, a noise detection unit and a controller, wherein the controller is arranged on the water heater body; the noise detection unit is arranged on the edge of a combustion chamber of the water heater body; and the controller controls the working condition of the fire grate in the combustion chamber according to a detection value of the noise detection unit. According to the water heater noise self-adaptive control method and the water heater provided by the invention, whether the air pressure of the water heater is normal or not can be accurately judged, and the water heater can stably burn under the condition that the air pressure is unstable.
Description
Technical field[0001]The invention belongs to the technical field of water heaters, and in particular relates to a water heater noise adaptive control method and a water heater.Background technique[0002]Most of the existing gas water heaters are AC-extracted gas water heaters (fans are not adjustable). When users use water, the gas water heater detects the water flow signal, and the fan is turned on for cleaning. The exhaust gas in the water heater is discharged through the smoke pipe, and the air pressure switch detects After it is closed, ignition is carried out, the gas valve is opened, and then it is burned. After the water is heated, it flows out through the water heater.[0003]Before each ignition or during the combustion process, it is necessary to judge whether the signal of the air pressure switch is closed. Closed means that the air duct is unobstructed and the air pressure system is normal. Due to strong external wind, or accidental blockage of the smoke pipe, and the sign...
