[0037] The present application will be further described below by way of examples, but the present application is not limited in the scope of the examples.

[0038] Example 1

[0039] The embodiment provides a control method of a ventilation fan, as shown in the figure, the ventilation fan comprises an air inlet fan 1, an air outlet fan 2 and a heating component 3. Figure 1

[0040] Specifically, as shown in the figure, the control method comprises: Figure 2

[0041] S101, obtaining a difference between an outlet water temperature of a water heater and an indoor temperature; wherein the water heater and the ventilation fan are both arranged in the indoor.

[0042] S102, adjusting a rotating speed of the air inlet fan, adjusting a rotating speed of the air outlet fan and controlling operation of the heating component according to the difference and a preset temperature; wherein the preset temperature is determined according to water vapor in the indoor.

[0043] Specifically, in the embodiment, the critical temperature difference for generating water vapor is different in different environments, so the preset temperature is set according to the critical temperature difference for generating water vapor. However, the value of the preset temperature is not limited herein, and is set according to specific conditions.

[0044] In an optional embodiment, S101 specifically comprises: obtaining the outlet water temperature of the water heater and the indoor temperature; and calculating the difference between the outlet water temperature and the indoor temperature.

[0045] In another optional embodiment, S101 specifically comprises: obtaining the difference between the outlet water temperature of the water heater and the indoor temperature from the water heater.

[0046] In the embodiment, as shown in the figure, S102 specifically comprises: Figure 3

[0047] S21, judging whether the difference is less than the preset temperature, if yes, executing step S22, and if no, executing S23.

[0048] S22, controlling the air inlet fan and the air outlet fan to operate at a first rotating speed, and controlling the heating component to stop operating.

[0049] S23, controlling the air inlet fan and the air outlet fan to operate at a second rotating speed, and controlling the heating component to operate; wherein the second rotating speed is greater than the first rotating speed.

[0050] ​​​Specifically, if the difference is less than the preset temperature set according to the critical temperature difference, it indicates that the speed of water vapor generation in the room is relatively slow, at this time, the air inlet fan and the air outlet fan are controlled to run at the first rotating speed, and the heating component is controlled to stop running. While reducing power consumption, it can reduce the water vapor in the room. When the difference is greater than or equal to the preset temperature set according to the critical temperature difference, it indicates that the speed of water vapor generation in the room is relatively fast, in order to prevent excessive water vapor from accumulating in the room, the air inlet fan and the air outlet fan are controlled to run at the second rotating speed, and the heating component is controlled to run, so as to timely discharge a large amount of water vapor in the room and improve the indoor temperature, and reduce the speed of water vapor generation in the room. Such control mode realizes intelligent control of the ventilation fan, thereby avoiding the defect of water vapor accumulation caused by forgetting to manually start the ventilation fan, and improving the comfort of the user during bathing.

[0051] In an optional embodiment, two temperature probes are installed in the room, one of which can be installed on the water heater for real-time detection of the water outlet temperature of the water heater, and one of which can be installed in the room for real-time detection of the indoor temperature; the ventilation fan further comprises a first main control unit and a second main control unit, and optionally, a microcontroller (MCU) is used as the first main control unit and the second main control unit, the first main control unit is arranged in the water heater, and the second main control unit is arranged in the ventilation fan; the heating component can be an electric heating wire or an infrared heating lamp; the air inlet fan and the air outlet fan are apart by X centimeters, and the value of X is set according to specific conditions to ensure that the air discharged by the air outlet is not sucked into the air inlet, thereby avoiding that the water vapor of the air outlet is sucked into the air inlet.

[0052] In use, when the first main control unit detects that the user opens the water heater to start bathing, the water outlet temperature of the water heater and the indoor temperature are obtained, the difference between the water outlet temperature of the water heater and the indoor temperature is calculated, and it is judged whether the difference is less than the preset temperature, and the difference is sent to the second main control unit; or the second main control unit obtains the water outlet temperature of the water heater and the indoor temperature, and calculates the difference. If the difference is less than the preset temperature, the second main control unit controls the air inlet fan and the air outlet fan to run at the first rotating speed, and controls the electric heating wire to stop running; if the difference is greater than or equal to the preset temperature, the second main control unit controls the air inlet fan and the air outlet fan to run at the second rotating speed, and controls the electric heating wire to run. In the above process, if the first main control unit detects that the water heater is closed, the second control unit controls the air inlet fan and the air outlet fan to be closed and controls the electric heating wire to stop running.

[0053] Preferably, in the above process, if the first master control unit detects that the water heater is off, the delay-off function can be started, for example, after two minutes, the air inlet fan and the air outlet fan are controlled to be off, and the electric heating wire is controlled to stop running. If the first master control unit detects that the water heater is on, the delay-off time in the delay-off function is cleared. The delay time can be set according to actual conditions, and is not limited to two minutes.

[0054] In the embodiment, a control method of a ventilation fan is provided. The control method can automatically adjust the rotating speed of the air inlet fan, adjust the rotating speed of the air outlet fan, and control the operation of the heating component according to the relationship between the indoor temperature and the water outlet temperature of the water heater, without manual operation, to achieve intelligent control, reduce indoor water vapor, reduce the water vapor generation rate, and improve the comfort of the user during bathing.
