Problems solved by technology

When the gas water heater is ignited, due to the influence of the external environment, including the difference between its own components, the mismatch between the amount of air and the gas will cause abnormal vibration during combustion. In some cases, the vibration occurs more frequently and the noise generated is relatively large. , which will affect the normal life of users
[0003] The current technology cannot detect the occurrence of this vibration problem. The current measures to avoid vibration are to design the working parameters of the proportional valve and fan at each stage in the early stage of research and development to achieve the best matching effect. However, in actual use, due to Vibration problems cannot be avoided due to differences in user environments and parts, and the existing technology does not deal with later vibrations, which will affect user experience

Embodiment 1

[0037] Such as figure 1 As shown, the first aspect of the present invention proposes a gas water heater control method with an acceleration sensor, the steps comprising:

[0038] S1, when the water flow sensor detects the water flow signal, start the gas water heater;

[0039] S2, the acceleration sensor arranged on the burner detects the vibration frequency of the burner in real time;

[0040] S3, sending the vibration frequency detected by the acceleration sensor to the single-chip microcomputer;

[0041] S4. The single-chip microcomputer determines the working mode of the gas water heater according to the vibration frequency detected by the acceleration sensor.

[0042] In the above technical solution, a water flow sensor is installed on the water inlet pipe of the gas water heater. When the user needs hot water and opens the valve of the water inlet pipe to feed water to the gas water heater, the water flow sensor will detect the water flow signal, and then the gas water...

Embodiment 2

[0066] Such as image 3 As shown, the steps of the gas water heater control method with acceleration sensor of the present invention are as follows:

[0067] S21, power on the gas water heater;

[0068] S22, when the water flow sensor detects the water flow signal, start the burner to ignite and burn;

[0069] S23, judging whether the vibration frequency signal output by the acceleration sensor is greater than or equal to a predetermined threshold, if the judging result is yes, go to step S25, otherwise go to step S24;

[0070] S24, the gas water heater continues to work normally according to the current working mode;

[0071] S25, the gas water heater increases or decreases the fan speed by 100-200rpm;

Abstract

The invention discloses a gas water heater with an acceleration sensor and a control method of the gas water heater. The control method of the gas water heater with the acceleration sensor comprises the steps that (1) after a water flow signal is detected by a water flow sensor, the gas water heater is started; (2) the acceleration sensor arranged on a combustor detects the vibration frequency of the combustor in real time; (3) the vibration frequency detected by the acceleration sensor is sent to a single chip microcomputer; and (4) according to the vibration frequency detected by the acceleration sensor, the single chip microcomputer determines the work mode of the water heater. In this way, the acceleration sensor is arranged on the combustor of the gas water heater so that the vibration condition of the combustor can be detected through the acceleration sensor. When the gas water heater is ignited for combustion, if the situation that vibration of the combustor is abnormal is detected, the combustion state of the gas water heater can be automatically adjusted, vibration of the combustor is reduced accordingly, and the situation that the combustor generates too large noise to disturb the normal life of a user is prevented.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a gas water heater with an acceleration sensor and a control method thereof. Background technique [0002] Gas water heaters use gas as the main energy source, and the high-temperature heat generated by gas combustion is transferred to the cold water flowing through the heat exchanger to achieve the purpose of preparing hot water. When the gas water heater is ignited, due to the influence of the external environment, including the difference between its own components, the mismatch between the amount of air and the gas will cause abnormal vibration during combustion. In some cases, the vibration occurs more frequently and the noise generated is relatively large. , which will affect the normal life of users. [0003] The current technology cannot detect the occurrence of this vibration problem. The current measures to avoid vibration are to design the working parameters of ...
