[0004] However, the existing disclosed oil cup liquid level detection device can only complete the detection of the liquid level in the oil cup, and then remind the user to clean the oil cup, and different users have different frequency of use of the range hood. If the range hood is not used, the oil stain in the oil cup will dry up. The existing oil cup liquid level detection device cannot detect whether the oil stain in the oil cup has dried up. It is also difficult to deal with applicability in the case of

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] When using the oil cup state detection method of the range hood in this embodiment, the memory of the range hood stores the relationship curve of Y-Y00 corresponding to the standard grease density oil for different oil cup shape parameters, where Y refers to It is the liquid level of standard grease density oil in the oil cup under normal conditions, and Y00 refers to the liquid level difference threshold for judging the dryness of standard grease density oil. The ratio parameter table of the grease density of different types of oils and the standard grease density is also stored, which is convenient for use in the following methods. When the range hood is in use, the user can choose the type of oil used for cooking, and then conveniently determine the ratio parameter K of the oil density of the used oil to the standard oil density.

Abstract

The invention relates to a method for detecting the state of an oil cup of a range hood, which is characterized in that: the first liquid level data Y1 of the oil in the oil cup is detected and obtained after the range hood is shut down each time, and the first liquid level data Y1 of the oil in the oil cup is detected and obtained each time the range hood is turned on. The second liquid level data Y of the oil in the oil cup; calculate the oil level difference ΔY=Y1-Y in the oil cup after the last shutdown of the range hood and the current startup, if ΔY≥Y0, then judge the oil in the oil cup In the case of dry binding, Y0 is the liquid level difference threshold for dry binding. The method for detecting the state of the oil cup of the range hood in the present invention can promptly remind the user to clean the oil stain in the oil cup, prevent the oil from drying up and increase the difficulty of cleaning for the user, and prevent the oil stain in the oil cup from being aggravated by continued use. Difficulty of cleaning.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a method for detecting the state of an oil cup of the range hood. Background technique [0002] The cleaning of the range hood is a long-standing and difficult problem, and the state judgment and cleaning method of the oil cup are also the contents of more attention in the range hood field. Publication No. CN109028198A (Application No. 201810941694.7) Chinese Invention Patent "An Oil-Full Self-Reminder Type Oil Collection Cup", in which the disclosed oil collection cup includes an oil detection device, which can pass the detection set Whether there is oil stain on the mouth of the oil cup body; when the oil stain on the oil cup body reaches the mouth of the cup, an alarm signal is sent; when in use, the oil quantity detection device installed on the cup mouth of the oil cup body is used to detect the cup The pressure of the mouth is used to monitor whether the oil in the oil...
