Problems solved by technology

Therefore, when the water pump is turned on for the same time, the amount of water sucked up by the water pump through the water pipe will vary according to the water temperature. In the case of a certain heater power, it will affect the temperature rise of the water heated by the heater. , that is, the less water is absorbed, the temperature rises, and the amount of steam ejected is large, which is beneficial to the decomposition of oil stains and helps to improve the cleaning effect; It is beneficial to the decomposition of oil stains, which will reduce the cleaning effect

Embodiment 1

[0021] The embodiment of the present invention provides a control method for the steam generation stage in the automatic cleaning process of the range hood, such as figure 1 As shown, the method is implemented by the following steps:

[0022] Step 101: Determine the working time corresponding to the first water temperature or the first ambient temperature and the working time corresponding to the second water temperature or the second ambient temperature, respectively, for the water pump with a fixed working cycle;

[0023] Specifically, when the cleaning function is activated, the detected temperature is T by detecting the water temperature of the water suction port of the water pump or the temperature of the external environment. , in the steam generation stage, the fixed duty cycle of the pump is t 0 , the total working time t of the pump in the steam generation stage, and the working time of each fixed working cycle of the pump is t 1 , the water temperature or ambient t...

Embodiment 2

[0037] The embodiment of the present invention also provides a control method for the steam generation stage in the automatic cleaning process of the range hood, such as figure 2 As shown, the method is implemented by the following steps:

[0038] Step 201: The water pump corresponds to the work cycle corresponding to the third water temperature or the third ambient temperature and the work cycle corresponding to the fourth water temperature or the fourth ambient temperature with a fixed working time in advance;

[0039] Specifically, when the cleaning function is activated, the detected temperature is T by detecting the water temperature of the water suction port of the water pump or the temperature of the external environment. In the steam generation stage, the working cycle of the pump is t 0 , the total working time t of the pump in the steam generation stage, and the working time of each fixed working cycle of the pump is t 1 , the water temperature or ambient temperat...

Abstract

The invention discloses a method for controlling the steam generation stage in the automatic cleaning process of range hoods. According to the water pump, the working time corresponding to the first water temperature or the first ambient temperature and the second water temperature or the second water temperature are respectively corresponding to the fixed working cycle in advance. 2. Determine the primary linear function or segmental function for the working time corresponding to the ambient temperature. In the steam generation stage of the automatic cleaning of the range hood, determine the current water temperature of the water pump suction port or the corresponding ambient temperature according to the primary linear function or segmental function. operating hours. The present invention adds parameters of water temperature or ambient temperature at the water suction port, which can adapt to different external ambient temperatures or changes in different seasons, and maintain the performance of the cleanliness in the cleaning process.

Description

technical field [0001] The invention belongs to the technical field of range hood cleaning, and in particular relates to a control method for a steam generation stage in an automatic cleaning process of a range hood. Background technique [0002] The automatic cleaning process of the range hood generally controls the heating logic according to the tested heater temperature or the water temperature after the heater is heated. However, due to the change of the external ambient temperature, the heating speed of the heater will be different. At the same time, due to the change of the external temperature, the hardness of the pipe wall of the suction water pipe (the water pipe is generally made of plastic material) connected to the water pump will change. , At the same time, due to thermal expansion and cold contraction, the thickness of the water pipe will change. These factors will affect the change of the water absorption capacity of the pump, thereby affecting the cleanliness...
