Description

Technical Field

[0001] This invention relates to the field of range hood technology, and in particular to a method for cleaning the back of a range hood. Background Technology

[0002] A range hood is a kitchen appliance that purifies the environment by continuously removing smoke, fumes, and moisture generated during cooking, thus reducing kitchen pollution and purifying the air. Currently, users typically need to manually turn off the range hood after cooking. More intelligent models usually shut off automatically after a one-minute delay. However, due to varying cooking needs, the fixed cleaning time after hood operation can lead to insufficient cleaning and lingering fumes, or forgetting to turn off the range hood can result in excessively long cleaning times and high-power fan operation, consuming excessive energy. Furthermore, some range hoods require a cooktop-range hood linkage function or manual operation to remove smoke during cooking. Summary of the Invention

[0003] The purpose of this invention is to provide a method for cleaning a range hood that can automatically turn on and adjust the cleaning time according to the concentration of cooking fumes, thereby providing at least one beneficial option or creating conditions to solve one or more technical problems existing in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] A method for cleaning the back of a range hood, which mainly includes the following steps.

[0006] 1) Set several oil fume concentration ranges and several cleaning times after the range hood, with each oil fume concentration range and cleaning time after the range hood corresponding to the other.

[0007] 2) Set the range of oil fume concentration after cleaning is completed.

[0008] 3) When cleaning is started, determine the maximum value Q of oil fume within a continuous time period. 烟max The range hood is controlled to perform post-cleaning based on the range hood's post-cleaning time corresponding to the range hood's concentration range.

[0009] 4) After cleaning is completed, measure the oil fume concentration value Q. 烟 If Q 烟 If the concentration of oil fumes exceeds the upper limit of the range, perform a follow-up cleaning for N times the duration, where N > 1; if Q 烟 If the concentration falls within the range of oil fume concentration, perform a post-cleaning cycle of M times the duration, where 0 < M ≤ 1; if Q 烟 If the concentration of oil fumes is less than the lower limit of the range, the subsequent cleaning procedure will end.

[0010] More preferably, the continuous time period should be selected within 3-30 seconds.

[0011] More preferably, the oil fume concentration value Q 烟 This is detected by an oil fume sensor.

[0012] More preferably, the range of oil fume concentration is based on the standard value Q of oil fume concentration. 标 Based on the benchmark, the Q is obtained. 标 It refers to the ambient oil fume level that the range hood is required to operate at.

[0013] More preferably, the standard value Q for oil fume concentration is... 标 These are empirical or experimental values.

[0014] More preferably, the lower limit of the oil fume concentration range is 0.5-1.0 Q. 标 Choose appropriately within the range; the upper limit of the fume concentration range is 1.2-2.0 Q. 标 Choose appropriately from among them.

[0015] More preferably, when the detected oil fume concentration is greater than or equal to Q 标 At this time, the range hood will continue to operate or turn on automatically.

[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Additional aspects and advantages of the invention will become apparent in the following description or may be learned by practice of the invention.

[0023] Reference Figure 1 As shown in one embodiment, the control flow of the range hood cleaning method is as follows.

[0024] 1) Set several oil fume concentration ranges and several cleaning times after the range hood, with each oil fume concentration range and cleaning time after the range hood corresponding to the other.

[0025] 2) When cleaning is started, determine the maximum value Q of oil fume within a continuous time period. 烟max The range hood is controlled to perform post-cleaning based on the range hood's post-cleaning time corresponding to the range hood's concentration range.

[0026] 3) After cleaning is completed, measure the oil fume value Q. 烟 If Q 烟 ≥1.5Q 标 If so, continue with a cleanup process that lasts twice as long. If 1.5Q 标 >Q 烟 ≥Q 标 If Q continues for the same duration, then another cleaning session will be performed. 烟 <Q 标 Then the cleaning process ends.

[0027] Among them, Q 标 The ambient oil fume level that the range hood needs to operate at is the specified value. This value can be an empirical value or an experimental value.

[0028] In this embodiment, the oil fume value is obtained by an oil fume sensor. The preferred continuous time period is 10 seconds, i.e., the maximum oil fume value Q is determined within 10 seconds. 烟max The system determines the range of oil fume concentration and then updates the corresponding post-cleaning time. Obviously, those skilled in the art can appropriately change the duration of the continuous time period according to different actual needs, such as selecting a range of 3-30 seconds; this is not limited to this embodiment.

[0029] It should be noted that in some embodiments, other ranges of oil fume concentration can be used instead of 1.5Q. 标 -Q 标 The oil fume value Q after cleaning is completed 烟If the fume concentration exceeds the upper limit of the range, perform a follow-up cleaning for N times the duration, where N > 1; the fume concentration Q at the end of the follow-up cleaning is... 烟 If the fume concentration falls within the range specified by the oil fume concentration, perform a follow-up cleaning for a duration of M times, where 0 < M ≤ 1; the oil fume value Q at the end of the follow-up cleaning is... 烟 If the concentration of oil fumes is less than the lower limit of the range, the subsequent cleaning procedure will end.

[0030] The range hood cleaning method provided in this embodiment can automatically adjust the cleaning time according to cooking needs. For example, the more oil fumes during cooking, the longer the cleaning time. It also has real-time monitoring of oil fume quality, enabling intelligent operation of the range hood and further adjusting the cleaning time to achieve optimal kitchen air quality after cooking while significantly reducing the energy consumption of the range hood fan during high-power operation.

[0031] When cooking, if the range hood is not manually turned on, the range hood sensor detects the oil fume level Q. 烟 ≥Q 标 It can also automatically turn on the range hood.
