Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a method and apparatus for cleaning a range hood, and a range hood. Background Technology

[0002] Currently, range hoods are essential kitchen appliances, allowing users to enjoy cooking more comfortably by removing cooking fumes. When the range hood is running, it draws in cooking fumes through the intake and filters them through a mesh screen to reduce grease buildup on the inner walls and internal components. However, after a period of use, a significant amount of grease will accumulate, requiring regular cleaning.

[0003] Among the related technologies, some clean the various parts of the range hood by steam, hot water, or cleaning agents; however, this cleaning method results in a complex product structure and generally poor cleaning effect. Other methods involve heating and cleaning by resistance heating, heating tube heating, or electromagnetic heating, but these methods have low electrothermal conversion efficiency and complex structures.

[0004] In the process of implementing the embodiments of this disclosure, it has been found that at least the following problems exist in the related technology: using the same cleaning method for all parts of the range hood results in some parts not being cleaned thoroughly, or over-cleaning causing a waste of resources. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides a method, apparatus, and range hood for cleaning range hoods, in order to solve the technical problem of resource waste caused by incomplete or excessive cleaning of range hood components.

[0007] In some embodiments, the range hood includes a plurality of components configured with an electrothermal coating structure; the method for cleaning the range hood includes: in response to a cleaning command, determining the range hood components to be cleaned; if there are a plurality of range hood components to be cleaned, determining the heating sequence among the plurality of range hood components to be cleaned, and the heating temperature corresponding to each of the plurality of range hood components to be cleaned; and controlling the range hood components to be cleaned to soften the grease in the heating sequence and their respective heating temperatures.

[0008] In some embodiments, the apparatus includes: a determining module, which, in response to a cleaning command, determines a range hood component to be cleaned, and, if there are multiple range hood components to be cleaned, determines a heating sequence among the multiple range hood components to be cleaned, and a heating temperature corresponding to each of the multiple range hood components to be cleaned; and a heating module, configured to control the range hood components to be cleaned to be heated and cleaned according to the heating sequence and their respective heating temperatures, thereby softening the grease.

[0009] In some embodiments, the apparatus includes a processor and a memory storing program instructions, the processor being configured to perform the above-described method for cleaning a range hood when executing the program instructions.

[0010] In some embodiments, the range hood includes: a plurality of electrically heated coated range hood components; an oil cup disposed on the smoke inlet side of the range hood; and the aforementioned device for cleaning the range hood.

[0011] The method, apparatus, and range hood for cleaning provided in this disclosure can achieve the following technical effects:

[0012] When the range hood responds to a cleaning command, if there is only one component to be cleaned, the heating temperature of that component can be determined, and the component can be controlled to soften grease under that temperature. If there are multiple components to be cleaned, the heating sequence and individual heating temperatures of each component can be determined, and the components can be controlled to soften grease under those specific temperatures. This approach allows for different cleaning methods for different components, such as different heating temperatures and different heating priorities. Compared to using the same cleaning method for all components, the solution provided in this disclosure is more targeted, improving the cleaning effect of each component. Furthermore, it is more rational, helping to solve problems such as insufficient cleaning of some components leading to poor cleaning results, or over-cleaning of some components resulting in wasted cleaning resources.

[0021] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0023] Unless otherwise stated, the term "multiple" means two or more.

[0024] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0025] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0026] Combination Figure 1 As shown, this disclosure provides a method for cleaning a range hood, the range hood including multiple components configured with an electrothermal coating, comprising the following steps:

[0027] S101, in response to a cleaning command, identifies the range hood components to be cleaned.

[0028] As an example, cleaning commands can be obtained either through user button selection or by automatically activating the self-cleaning function of the range hood. For instance, if the range hood control panel has a cleaning button, the user can select whether to activate the cleaning command based on the level of grease buildup. Alternatively, if the range hood has a self-cleaning function, the user can select whether to activate the cleaning command based on parameters such as runtime.

[0029] Optionally, the operating status of the range hood can be obtained, and when the operating status indicates that the range hood is in a non-working state, i.e., a non-cooking state, the cleaning command can be responded to and the range hood can be cleaned.

[0030] Since condensing oil fumes can improve the interception rate of oil fumes, turning on the oil fume cleaning function during cooking is not conducive to the interception of oil fumes. Therefore, range hood cleaning can be done when not cooking.

[0031] The range hood components to be cleaned can be one or more of multiple components equipped with an electrothermal coating, selected according to the user's cleaning needs, or determined by the range hood according to program settings. For example, the range hood can detect the degree of grease on each component and determine the components to be cleaned based on the degree of grease.

[0032] S102, when there are multiple range hood components to be cleaned, determine the heating sequence among the multiple range hood components to be cleaned, and the heating temperature corresponding to each of the multiple range hood components to be cleaned.

[0033] If there is only one part of the range hood to be cleaned, the heating temperature of the part can be determined based on its condition, such as the degree of oil contamination. In other words, different parts, or even the same part with different degrees of oil contamination, may correspond to different heating temperatures, making the oil softening process more targeted and reasonable, and helping to improve the cleaning effect.

[0034] If there are multiple range hood components to be cleaned, a cleaning priority can be set for each component, and the heating sequence among these components can be determined based on this priority. The cleaning priority can be preset in the range hood cleaning program or set according to cleaning needs; that is, the cleaning priority can be a fixed setting or a non-fixed setting. For example, a non-fixed setting could be based on user-input instructions, i.e., according to the user-defined cleaning order; or, the heating sequence could be randomly determined; or the heating sequence could be determined based on the degree of grease contamination, and so on. Optionally, the heating priority of the components to be cleaned can be determined based on their installation location, and the heating sequence among these components can be determined based on this priority.

[0035] In this embodiment, the heating sequence of the range hood components to be cleaned is determined based on their installation locations. For example, components such as the smoke hood and oil filter are installed on the outer surface of the range hood housing, while components such as the impeller and flue are installed inside the housing. The smoke hood and oil filter can be assigned the highest heating priority, followed by the impeller and flue. The installation locations of the range hood components can be differentiated according to different needs, and multiple priority levels can be established, not limited to the two levels mentioned above. After obtaining the heating priorities of multiple range hood components to be cleaned, the heating sequence among them can be determined.

[0036] The heating temperature of the range hood components to be cleaned can be determined based on the usage environment of the range hood. For example, commercial range hoods are used more frequently and produce more oil fumes, so the heating temperature of their components will be higher than that of household range hoods. Alternatively, it can be determined based on the degree of oil contamination on each component. For example, the grease filter is the first part to come into contact with oil fumes and is therefore more heavily contaminated, requiring a higher heating temperature. Or, the heating temperature of each component can be determined based on its function. For example, the grease filter is used to filter oil fumes and is prone to accumulating oil, requiring a higher heating temperature, and so on.

[0037] S103 controls the components of the range hood to be cleaned to soften the grease during the heating sequence and at their respective heating temperatures.

[0038] When there is only one range hood component to be cleaned, the component is heated at a set temperature to soften the grease on its surface. The softened grease then flows into the oil cup or oil tank under its own weight, thus achieving self-cleaning of the range hood component.

[0039] When there are multiple range hood components to be cleaned, the components are heated according to a set heating sequence and corresponding heating temperature. For example, taking the smoke hood and grease filter, impeller and flue as examples, the smoke hood and grease filter are set to have a high heating priority, followed by the impeller and flue. If the heating temperature for the smoke hood and grease filter is 90℃, and the heating temperature for the impeller and flue is 70℃, then the smoke hood and grease filter are heated first to 90℃ to soften the grease on their surface and allow it to flow into the grease cup. Then, the impeller and flue are heated to 70℃ to soften the grease on their surface and allow it to flow into the grease cup. In this embodiment, the heating sequence and temperature of each range hood component are determined according to their specific characteristics, achieving classified self-cleaning of the components and resulting in good cleaning performance.

[0040] Combination Figure 2 As shown in the embodiments of this disclosure, another method for cleaning a range hood is provided, including:

[0041] S201, in response to a cleaning command, identifies the range hood components to be cleaned.

[0042] In this embodiment, the acquisition of cleaning instructions and the determination of the range hood components to be cleaned can refer to step S101 in the above embodiment, and will not be repeated here.

[0043] S202, when there are multiple range hood components to be cleaned, determine the heating sequence among the multiple range hood components to be cleaned, and the heating temperature corresponding to each of the multiple range hood components to be cleaned; wherein, based on the height information of the multiple range hood components to be cleaned installed on the range hood, determine the heating priority of the range hood components to be cleaned, and determine the heating sequence among the multiple range hood components to be cleaned based on the heating priority.

[0044] In this embodiment, the installation position of the range hood component to be cleaned can be represented by the height information of the range hood component installed on the range hood. Based on the installation height information of the range hood component to be cleaned, the heating priority of the range hood component to be cleaned can be determined, and then the heating sequence of the range hood component to be cleaned can be determined.

[0045] Specifically, multiple priority levels can be defined according to usage requirements. Taking three heating priorities as an example, the highest priority level is represented by level 3, and the lowest priority level is represented by level 1. In addition, two preset positions can be predetermined: a first preset position and a second preset position, to define different height information, wherein the first preset position is higher than the second preset position.

[0046] For example, when the range hood components to be cleaned include a cleaning ring, impeller, volute, flue, smoke hood, and grease filter, and the location of the flue is set as the first preset position, and the location of the smoke hood is set as the second preset position, if the installation height of the range hood components to be cleaned is higher than the first preset position, grease softening treatment can be performed first, and the corresponding heating priority can be determined as level 3. In this example, the range hood components with heating priority level 3 can be the cleaning ring, impeller, and volute. If the installation height of the range hood components to be cleaned is less than or equal to the first preset position but greater than the second preset position, grease softening treatment can be performed second priority, and the corresponding heating priority can be determined as level 2. In this example, the range hood components with heating priority level 2 can be the flue and smoke hood. If the installation height of the range hood components to be cleaned is less than the second preset position, grease softening treatment can be performed last, and the corresponding heating priority can be determined as level 1. In this example, the range hood component with heating priority level 1 can be the grease filter.

[0047] Thus, after obtaining the heating priority of each range hood component to be cleaned, the heating sequence among multiple components can be determined. In this embodiment, the height of the range hood component to be cleaned is directly proportional to the heating priority. That is, when determining the heating priority based on the height information, the higher the installation position, the earlier the component is heated. This avoids heating and cleaning the components installed at lower positions first, and prevents secondary contamination of the already cleaned components at lower positions during the process of softening grease flowing into the grease cup, thereby improving cleaning efficiency.

[0048] The heating temperature for each component of the range hood to be cleaned can be determined based on its function. For example, the cleaning ring, impeller, and volute belong to the range hood's fan system and are core components; their cleanliness directly affects the quality of the exhaust fumes. Therefore, their heating temperature can be set to a higher temperature. The flue and fume hood, on the other hand, have little impact on the exhaust quality and can be heated to a lower temperature. Although the grease filter is not a core component, its cleanliness directly affects the range hood's appearance, so its heating temperature can be set to the second highest temperature.

[0049] S203 controls the components of the range hood to be cleaned to soften grease during the heating sequence and at their respective heating temperatures.

[0050] After determining the heating sequence and corresponding heating temperature of the cleaning range hood components in step S202, each range hood component is controlled to be heated and cleaned at the corresponding heating sequence and corresponding heating temperature to soften the grease and achieve self-cleaning of each component.

[0051] Combination Figure 3 As shown in the embodiments of this disclosure, another method for cleaning a range hood is provided, including:

[0052] S301, in response to a cleaning command, identifies the range hood components to be cleaned.

[0053] In this embodiment, the acquisition of cleaning instructions and the determination of the range hood components to be cleaned can refer to step S101 in the above embodiment, and will not be repeated here.

[0054] S302, when there are multiple range hood components to be cleaned, determine the heating sequence among the multiple range hood components to be cleaned, and determine the heating temperature of the range hood components according to the degree of oil contamination of the range hood components to be cleaned.

[0055] Optionally, the degree of oil contamination on the range hood components to be cleaned is directly proportional to the heating temperature.

[0056] In this embodiment, the heating temperature of multiple range hood components to be cleaned is determined based on the degree of grease contamination of the components. For example, when the range hood components to be cleaned include a cleaning ring, impeller, volute, flue, smoke hood, and grease filter, generally speaking, the impeller, cleaning ring, and volute have the heaviest grease, so their heating temperature is set to the highest; the grease filter has the next heaviest grease, so its heating temperature is set to the second highest; and the flue and smoke hood have the lightest grease, so their heating temperature is set to the lowest. Furthermore, the degree of grease contamination of the range hood components can be determined based on user input information. For example, based on the actual usage of the range hood, the user sets the grease filter to have the heaviest grease, followed by the impeller, cleaning ring, and volute, and the flue and smoke hood to have the lightest grease. In this case, the grease filter will have the highest heating temperature, the impeller, cleaning ring, and volute will have the next highest heating temperature, and the flue and smoke hood will have the lowest heating temperature.

[0057] In this embodiment, the heating temperature is determined according to the degree of oil contamination of the range hood components. The more severe the contamination, the higher the heating temperature, which is conducive to the thorough cleaning of the range hood components. This avoids the problem that some heavily contaminated range hood components are not cleaned properly when multiple components are heated at the same temperature, or that some lightly contaminated range hood components are over-cleaned, resulting in a waste of cleaning resources.

[0058] The degree of grease contamination on range hood components can be determined automatically by the range hood itself or based on user input. For example, automatic detection can employ image acquisition and processing, capacitive sensing, or photoelectric detection, among other methods. User input allows users to set the desired level of grease contamination for different components; for instance, the grease filter might be set to be the most heavily contaminated, followed by the impeller and volute, with the smoke hood and duct being the least contaminated.

[0059] S303 controls the heating sequence and corresponding heating temperature of the range hood components to be cleaned, thereby softening the grease.

[0060] Combination Figure 4 As shown in the embodiments of this disclosure, another method for cleaning a range hood is provided, including:

[0061] S401, in response to a cleaning command, identifies the range hood components to be cleaned.

[0062] In this embodiment, the acquisition of cleaning instructions and the determination of the range hood components to be cleaned can refer to step S101 in the above embodiment, and will not be repeated here.

[0063] S402, when there are multiple range hood components to be cleaned, the heating sequence among the multiple range hood components to be cleaned is determined based on the height information of the range hood components installed on the range hood, and the heating temperature of the range hood components is determined based on the degree of oil contamination of the range hood components to be cleaned.

[0064] In this embodiment, the heating sequence among multiple range hood components to be cleaned is determined based on the height information of the range hood components installed on the range hood, as described in S202 of the above embodiment; the heating temperature of the range hood components is determined based on the degree of oil contamination of the range hood components to be cleaned, as described in S303 of the above embodiment; these details will not be elaborated upon here.

[0065] S403 controls the heating sequence and corresponding heating temperature of the range hood components to be cleaned to soften the grease.

[0066] Optionally, when multiple range hood components to be cleaned are heated and the heating sequence and / or heating temperature of the multiple range hood components to be cleaned are inconsistent, the heating and cleaning is carried out according to the heating priority and / or heating temperature.

[0067] In this embodiment, when there are multiple range hood components with the same heating priority but different heating temperatures, the heating order of these components within the same heating priority level can be determined based on their respective heating temperatures. For example, the heating order can be from low to high temperature or from high to low temperature, depending on actual usage requirements. Alternatively, besides determining the heating order based on heating temperature, the heating order of multiple range hood components within the same heating priority level can also be determined by random sorting.

[0068] Furthermore, when the heating temperature is the same but the heating priority is different, the heating and cleaning are carried out sequentially according to the heating priority; when both the heating priority and the heating temperature are different, the heating is carried out at their respective heating temperatures according to the heating priority.

[0069] Here's an example illustrating different heating priorities and temperatures: For instance, the components to be cleaned in a range hood include a cleaning ring, impeller, volute, flue, smoke hood, and oil filter. The heating temperatures are set as follows: impeller, cleaning ring, and volute have the highest heating temperature; oil filter has the second highest; and flue and smoke hood have the lowest. The heating sequence is: Level 3 is impeller, cleaning ring, and volute; Level 2 is flue; and Level 1 is oil filter and smoke hood. The cleaning method is as follows: Level 3 impeller, cleaning ring, and volute are cleaned first at the highest temperature; Level 2 flue is cleaned second at the lowest temperature; finally, Level 1 smoke hood is cleaned first at the lowest temperature, and then oil filter is cleaned at the next highest temperature, or Level 1 oil filter is cleaned first at the next highest temperature, and then smoke hood is cleaned at the lowest temperature. This embodiment prioritizes multiple range hood components and uses different cleaning temperatures for different components to improve cleaning effectiveness, save resources, and prevent lightly soiled components from being repeatedly cleaned or heavily soiled components from being left uncleaned.

The determining module 21 is configured to determine the range hood components to be cleaned in response to a cleaning command, and, if there are multiple range hood components to be cleaned, determine the heating sequence among the multiple range hood components to be cleaned, as well as the heating temperature corresponding to each of the multiple range hood components to be cleaned; the heating module 22 is configured to control the range hood components to be cleaned to be heated and cleaned according to the heating sequence and their respective heating temperatures, thereby softening the grease.
