Embodiment 1

[0029] Embodiment 1 of the present invention provides an exhaust gas protection control method, which is applied to water heaters, and the control method includes the following method steps S1-S3:

[0030] S1, detecting the wind pressure value in the exhaust passage. When the water heater starts to work and generates exhaust gas, the wind pressure value in the exhaust passage is detected. When the external environment is windy or there are several other weather conditions, the detected wind pressure value is affected by the external resistance, which is less than the wind pressure value generated by the fan rotation; when the exhaust pipe is blocked, the detected wind pressure value The value is that the wind pressure generated by the rotation of the fan is affected by the blockage and cannot flow smoothly, so it is smaller than the value of the wind pressure generated by the rotation of the fan.

[0031] S2, when it is detected that the wind pressure value is lower than the ...

Embodiment 2

[0036] Embodiment 2 of the present invention provides an exhaust gas protection control method, which is applied to water heaters. On the basis of Embodiment 1, step S3 includes:

[0037] S31, when it is detected that the wind pressure value is lower than the preset wind pressure value and the fan speed is at the maximum, timing protection is performed to maintain the maximum fan speed;

[0038] S32. Obtain a corresponding protection period according to the difference between the calculated wind pressure value and the preset wind pressure value;

[0039] S33, when it is detected that the wind pressure value is greater than or equal to the preset wind pressure value during the protection period, the water heater continues to work, and when the wind pressure value is still lower than the preset wind pressure value after the protection period ends, the water heater stops working.

[0040] In this embodiment, before step S1, it also includes:

[0041] S0, preset and store a prese...

Embodiment 3

[0047] Embodiment 2 of the present invention provides a water heater applying the control method for preventing channel clogging, and implements the control method. The water heater includes an exhaust channel for discharging combusted flue gas, which also includes:

Abstract

The invention discloses an exhaust protection control method and a water heater applying the exhaust protection control method. The control method for preventing channel blockage is applied to a waterheater and comprises the steps that the air pressure value in an exhaust channel is detected; when it is detected that the air pressure value is lower than a preset air pressure value, the rotating speed of a fan is increased; and when it is detected that the air pressure value is lower than the preset air pressure value and the rotating speed of the fan is maximum, timing protection is conducted, and timing protection comprises the steps that a protection period is set, the rotating speed of the fan is kept maximum in the protection period, when it is detected that the air pressure value islarger than or equal to the preset air pressure value in the protection period, the water heater continues to work, and when it is detected that the air pressure value is still lower than the preset air pressure value after the protection period is finished, the water heater stops working. According to the control method, the water heater applying the control method can avoid the situation that the water heater is forcibly stopped frequently due to transient gust strong wind through timing protection, and meanwhile the problem that flue gas exceeds the standard due to the outside environment or channel blockage is solved.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to an exhaust gas protection control method and a water heater using the same. Background technique [0002] With the popularization and application of gas water heaters, it has brought great convenience to people's daily life. At the same time, in order to prevent safety accidents caused by insufficient combustion of gas or gas leakage, an exhaust fan is equipped to exhaust the waste gas generated by combustion. . However, when using a gas water heater, if the external wind pressure is too large or the pipe is blocked, the gas water heater will increase its smoke exhaust resistance during use, and the smoke exhaust efficiency of the strong exhaust fan will become lower, resulting in insufficient combustion, exhaust gas exceeding the standard, and water temperature. If it becomes lower, there will be potential safety hazards, which will cause great harm to ...
