Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a cleaning device for a range hood and a range hood including the same. Background Technology

[0002] Existing technology for range hoods has a significant drawback: during normal operation, the internal components such as the volute and impeller are not heated; heating only occurs during self-cleaning. Consequently, grease produced during cooking cools and solidifies rapidly upon contact with relatively cold metal surfaces like the volute and impeller.

[0003] Over time and with increased usage, these solidified greases gradually accumulate, forming a layer of stubborn, aged grease that is difficult to remove. New grease is drawn back into the range hood with each cooking cycle and adheres to this aged grease layer, further exacerbating the grease buildup problem. This not only affects the appearance of the range hood but, more importantly, reduces its efficiency and smoke extraction effectiveness.

[0004] Furthermore, even if users regularly activate the range hood's self-cleaning mode, some grease may be tightly bound to the internal structure of the device, and the effects of high-temperature heating and cleaning agents may not be able to completely remove all accumulated grease.

[0005] Therefore, the problem of cleaning oil stains after long-term use needs to be addressed in existing range hood technology. Summary of the Invention

[0006] In view of the above-mentioned problems in the prior art, the purpose of this application is to provide a range hood that can efficiently clean oil stains from a range hood.

[0007] To address the aforementioned problems, this application provides a cleaning device for a range hood and a range hood including the same. The cleaning device includes a heater, a detection component, and a controller; the controller is communicatively connected to the heater and the detection component, respectively.

[0008] The detection component is disposed on the housing of the range hood, and the detection component is used to detect the environment of the range hood and generate environmental information when the range hood is not running;

[0009] The controller is used to send heating control commands to the heater based on the environmental information;

[0010] The heater is disposed on the housing of the range hood and is located near the impeller assembly in the range hood. The heater is used to heat the housing near the impeller assembly based on the heating control command.

[0011] Preferably, the detection component includes a human body detector, which is disposed on the outer wall surface of the housing. The human body detector is used to collect the human body status located on the body of the range hood and generate human body information.

[0012] Preferably, the controller is further configured to send a first preheating command to the heater based on the human body information when it is determined that the distance is less than a first preset threshold.

[0013] The heater is also used to heat the housing near the wind turbine assembly based on the first preheating command.

[0015] The heater is also used to stop heating the housing near the wind turbine assembly based on the first stop preheating command.

[0016] Preferably, the detection component includes a resistance detector, which is disposed in the flue of the range hood. The resistance detector is used to collect the resistance status in the flue and generate resistance information.

[0017] Preferably, the resistance detector is further used to collect the resistance of the flue and generate first resistance information when the range hood is not turned on;

[0018] The controller is also configured to send a second preheating start command to the heater if it determines that the first resistance information is greater than the first preset resistance value.

[0019] The heater is also used to heat the housing near the wind turbine assembly based on the second preheating command.

[0020] Preferably, the resistance detector is further used to collect the resistance of the flue and generate second resistance information when the range hood is turned on;

[0024] The controller is also used to send a timed start command to the heater based on the timed start information;

[0025] The heater is also used to heat the housing near the wind turbine assembly based on the timed start command.

[0026] Preferably, the heater is also used to heat the housing near the impeller assembly to a temperature T1 when the range hood is not in operation;

[0027] The heater is also used to continue heating the housing near the impeller assembly to a temperature T2 while the range hood is running;

[0028] Wherein, the temperature T1 and / or the temperature T2 are within the temperature range of 50℃-75℃.

If preheating is required, the controller sends a heating control command to the heater, which then heats the housing near the impeller assembly to soften grease, making it easier to clean, improving cleaning efficiency, reducing grease buildup, slowing down the aging of range hood components, and extending its lifespan.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0043] The term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this application. In the description of this application, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0044] like Figures 6-7 As shown, this application discloses a range hood 200, which includes a fan assembly 21, a flue 22, and a cleaning device 100 for the range hood 200. The fan assembly 21 is disposed in the body of the range hood 200, and the flue 22 is connected to the air inlet of the range hood 200 through the fan assembly 21 and is disposed at the air outlet of the range hood 200.

[0045] like Figures 1-5 As shown, the cleaning device 100 includes a heater 11, a detection component 12, and a controller 13; the controller 13 is communicatively connected to the heater 11 and the detection component 12 respectively.

[0046] The detection component 12 is installed on the housing of the range hood 200. The detection component 12 is used to detect the environment of the range hood 200 and generate environmental information when the range hood 200 is not running.

[0047] Controller 13 is used to send heating control commands to heater 11 based on environmental information;

[0048] The heater 11 is disposed on the housing of the range hood 200 and is located near the impeller assembly 21 in the range hood 200. The heater 11 is used to heat the housing near the impeller assembly 21 based on the heating control command.

[0049] Understandably, when the range hood 200 is not in operation, the detection component 12 can detect the surrounding environment of the range hood 200, generate environmental information, and send the environmental information to the controller 13. The controller 13 can make a judgment based on the received environmental information, and under the condition that the preset requirements are met, it can generate a heating control command and send it to the heater 11. The heater 11 then activates its preheating function according to the received heating control command, so as to heat the housing near the area of ​​the impeller assembly 21.

[0050] The main purpose of the technical means proposed in this application is to soften grease stains by heating components such as the volute when the range hood 200 is not in operation, making it easier to clean. Thus, by heating the volute, the grease stains can be discharged through the flue 22 before they solidify, thereby reducing the accumulation of grease stains inside the range hood 200.

[0051] Therefore, by setting up the detection component 12, environmental information around the range hood 200 can be detected, specifically including whether someone is approaching and the resistance within the internal flue 22 of the range hood 200. Then, the controller 13 determines whether the preheating function of the heater 11 needs to be activated based on the environmental information provided by the detection component 12. If the preheating function needs to be activated, the controller 13 sends a heating control command to the heater 11, which then heats the housing near the impeller assembly 21 according to the heating control command to soften the grease, making it easier to clean, improving cleaning efficiency, reducing grease accumulation, slowing down the aging of the range hood 200 components, and extending its service life.

[0052] like Figures 2-3 As shown, the detection component 12 includes a human body detector 121, which is preferably disposed on the outer wall of the housing. The human body detector 121 is used to collect the human body status of the body located in the range hood 200 and generate human body information.

[0053] Understandably, the human body detector 121 can detect human body information around the range hood 200, generate human body information, and send it to the controller 13. After receiving the human body information, the controller 13 can make a judgment and then decide whether to send a heating control command to the heater 11.

[0054] In this embodiment, the human body detector 121 generates the human body information by collecting the distance of the human body around the range hood 200 relative to the range hood 200. It can be understood that the controller 13 also determines whether to send a heating control command to the heater 11 based on the distance of the human body information and its relationship with the preset distance.

[0055] Preferably, the human body detector 121 in this application can be a radar or infrared sensor, etc.

[0056] Therefore, at least the following two cases are included:

[0057] In the first case: the controller 13 is also used to send a first preheating command to the heater 11 based on the human body information L1 when it is determined that the human body information L1 is less than the first preset distance threshold L01.

[0058] Heater 11 is also used to heat the housing near the wind turbine assembly 21 based on the first preheating command.

[0059] In this embodiment of the application, the first preset distance threshold L01 = 60cm.

[0060] Understandably, when the range hood 200 is not turned on, if a person is within the first preset distance threshold of the range hood 200, the controller 13 can determine that the person intends to use the range hood 200. Therefore, before turning on the range hood 200, the housing around the impeller assembly 21 is preheated. This prevents grease from adhering to the housing when the person uses the range hood 200. The preheated volute and other components effectively prevent grease adhesion, ensuring smooth exhaust of grease and reducing grease accumulation. This prepares the range hood 200 for subsequent use, maximizing grease removal. Therefore, by preheating, grease adhesion on the impeller assembly 21 and other components can be minimized, thereby improving cleaning efficiency and reducing the frequency and difficulty of cleaning.

[0061] In the second scenario, the controller 13 is also used to send a first stop preheating command to the heater 11 when it is determined that the human body information L2 is greater than the second preset distance threshold L02.

[0062] Heater 11 is also used to stop heating the housing near the wind turbine assembly 21 based on the first stop preheating command.

[0063] In this embodiment of the application, the second preset distance threshold L02 = 80cm.

[0064] Understandably, when the range hood 200 is not turned on, if a person is outside the second preset distance threshold of the range hood 200, the controller 13 can determine that the person will not use the range hood 200. Therefore, before the range hood 200 is turned on, if the controller detects that the person is at a certain distance from the range hood 200, it will control the heater 11 to stop heating to avoid unnecessary energy consumption. Thus, by detecting the distance of the person relative to the range hood 200, intelligent control of the preheating function is achieved, which is more in line with the user's actual usage habits.

[0065] In this application embodiment, the numerical range provided for the first preset distance threshold L01 and the second preset distance threshold L02 is basic data, and the specific values ​​can be obtained as final parameters after actual product performance testing.

[0066] like Figures 4-5 As shown, the detection component 12 includes a resistance detector 122, which is installed in the flue 22 of the range hood 200. The resistance detector 122 is used to collect the resistance status in the flue 22 and generate resistance information.

[0067] It is understandable that the resistance detector 122 can detect the resistance in the flue 22 of the range hood 200, generate resistance information, and send it to the controller 13. After receiving the resistance information, the controller 13 can make a judgment and then decide whether to send a heating control command to the heater 11.

[0068] In this embodiment, the controller 13 determines whether to send a heating control command to the heater 11 by judging the magnitude of the resistance information received from the resistance detector 122 and comparing it with a preset resistance value.

[0069] Preferably, the resistance detector 122 in this application can be a pressure sensor or the like.

[0070] Therefore, at least the following two cases are included:

[0071] In the first scenario: the resistance detector 122 is also used to collect the resistance of the flue 22 and generate the first resistance information Z1 when the range hood 200 is not turned on.

[0072] The controller 13 is also used to send a second preheating command to the heater 11 based on the first resistance information Z1 when it is determined that the first resistance information Z1 is greater than the first preset resistance value Z01.

[0073] The heater 11 is also used to heat the housing near the wind turbine assembly 21 based on the second preheating command.

[0074] It is understandable that when the range hood 200 is not turned on, if the controller 13 determines that the first resistance information Z1 is greater than the first preset resistance value Z01, the controller 13 can determine that the cooking period is currently underway. Therefore, the controller 13 will send a second preheating command to the heater 11, enabling the heater 11 to activate the preheating function. This prevents grease from accumulating on the casing when the range hood 200 is subsequently turned on. Specifically, as... Figure 7 As shown, the resistance detector 122 in this application can detect the resistance in the public flue. By detecting the amount of oil fumes flowing into the public flue from other households, it generates first resistance information Z1. After receiving the first resistance information Z1, the controller 13 determines that the current time period is the cooking time when it determines that the user will also be cooking and generating oil fumes. Therefore, the controller 13 sends a second preheating command to the heater 11, so that the heater 11 can turn on the preheating function of the range hood 200 before the user starts cooking. This prevents oil stains from adhering to the volute and other parts before preheating. By preheating in time, the adhesion of oil stains to the volute and other parts can be minimized, thereby improving cleaning efficiency and reducing the number of cleaning times and difficulty.

[0075] In the second scenario, the resistance detector 122 is also used to collect the resistance of the flue 22 and generate second resistance information Z2 when the range hood 200 is turned on.

[0076] The controller 13 is also used to send a second stop preheating command to the heater 11 based on the second resistance information Z2 when it is determined that the resistance information Z2 is less than the second preset resistance value Z02.

[0077] Heater 11 is also used to stop heating the housing near the wind turbine assembly 21 based on the second stop preheating command.

[0078] Among them, Z1>Z2.

[0079] Understandably, when the range hood 200 is on, if the controller 13 detects that the second resistance information Z2 is less than the second preset resistance value Z02, the controller 13 can determine that the cooking period is no longer in effect. The controller 13 will then control the heater 11 to stop heating to avoid unnecessary energy consumption. Specifically, the resistance detector 122 detects the fumes in the common flue and generates the second resistance information Z2. Upon receiving the second resistance information Z2, if the controller 13 determines that the second resistance information Z2 is less than the second preset resistance value Z02, the controller 13 can determine that the current period is no longer a cooking period and will send a second stop preheating command to the heater 11 to shut down the cleaning device 100. Therefore, by detecting changes in resistance within the flue 22, it can automatically identify whether the user has finished cooking without manual intervention. When a non-cooking state is detected, the preheating function is immediately stopped to avoid unnecessary energy consumption. By stopping preheating in a timely manner, the user's electricity bill can be reduced, energy efficiency can be improved, and the environment can be more environmentally friendly.

[0080] Preferably, the cleaning device 100 of this application further includes a timer, which is communicatively connected to the controller 13, and the timer is used to generate timed start information based on a preset time.

[0081] The controller 13 is also used to send a timed start command to the heater 11 based on the timed start information;

[0082] Heater 11 is also used to heat the housing near the wind turbine assembly 21 based on the timed start command.

[0083] In this embodiment, the timer can be electrically connected to the controller 13 to display the time via cloud acquisition. This allows for remote control and timer setting, which is more convenient. Alternatively, the timer can be a built-in timer of the range hood 200 that is electrically connected to the controller 13 to display the time. This avoids dependence on network connection and is more reliable.

[0084] Understandably, users can pre-set the time on the timer to activate the preheating function of heater 11.

[0085] Therefore, by designing a timer, users can preset the preheating time according to their lifestyle habits, such as preheating before cooking each day to avoid grease buildup; or, users can adjust the preheating time according to their needs, such as adjusting the length of the preheating time or setting multiple preheating times. In this way, with timed preheating, users no longer need to manually turn on the preheating function before each use of the range hood, making it more convenient.

[0086] In this embodiment of the application, the heater 11 is also used to heat the housing near the impeller assembly 21 to a temperature T1 when the range hood 200 is not running; and the heater 11 is also used to continue to heat the housing near the impeller assembly 21 to a temperature T2 when the range hood 200 is running.

[0087] Temperatures T1 and / or T2 are within the range of 50℃ to 75℃. The specific temperature settings can be adjusted in the actual product, for example, according to the viscosity of the oil stains or the user's usage habits.

[0088] Therefore, by heating components such as the volute to 50℃-75℃, grease stains can be effectively softened, making them easier to clean. Furthermore, controlling the temperature between 50℃ and 75℃ can also prevent high temperatures from damaging the components of the range hood and extend its service life.
