DETAILED DESCRIPTION

[0035] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] 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 the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0038] In the related art, the inner wall of the volute of a traditional range hood comes into contact with oil smoke during use, and will absorb a lot of oil stains. The longer the time, the more difficult it is to clean the formed oil stains. Such oil stains are difficult for users to clean by themselves. In view of this, one of the core concepts of an embodiment of the present invention is that the present invention provides a range hood and a cleaning control method thereof. When in use, the range hood and the control method thereof can transport a mixed liquid formed by a mixture of cleaning microorganisms, a culture solution and a product of cleaning microorganisms to the interior of the volute, and utilize the kinetic energy of the rotation of the fan combined with the oil cleaning function of the microorganisms to clean the grease in the volute, thereby deeply cleaning the oil stains on the inner wall of the volute, and avoiding user inconvenience and corresponding safety hazards caused by the accumulation of oil stains.

[0039] In one aspect, the present invention provides a range hood.

[0040] Reference Figure 1 , shows a structural diagram of a range hood provided by an embodiment of the present invention, and the range hood may specifically include the following modules:

[0041] The range hood body 10 in one embodiment includes a volute 110 and a microbial cleaning device 200; the microbial cleaning device is responsible for cleaning the oil stains on the inner wall of the volute in the range hood; the microbial cleaning device 200 includes a culture dish 220, a monitoring device 210 and a transport device 230. When executing the cleaning procedure, the mixed liquid in the culture dish 220 is transported into the interior of the volute 110 by the transport device 230 under the action of a power device (not shown in the drawings), thereby cleaning the oil stains on the inner wall of the volute.

[0042] In the above embodiment, a range hood is provided that cleans the range hood volute based on microorganisms, which mainly uses the centrifugal force generated by the rotation of the impeller to cause the bubbles in the mixed solution to explode; the energy released by the explosion and the physical effect are coordinated with the active substances in the mixed solution to clean the grease accumulation inside the volute 110 inside the range hood body 10, and the culture dish 220 of the microbial cleaning device 200 stores the mixed solution. The mixed solution combines the decomposition effect of microorganisms with the explosion effect of bubbles to convert the oil stains inside the volute 110 inside the range hood body 10 into harmless carbon dioxide, water and fine oil molecules, thereby cleaning the oil stains; when in use, the mixed solution is transported to the volute 110 inside the range hood body 10 through the transportation device 230; the decomposition effect of microorganisms on the oil stains is coordinated with the explosion effect of bubbles, and the volute 110 inside the range hood body 10 can be automatically cleaned without human intervention to keep it clean and hygienic, thereby preventing the load of the suction and exhaust system from increasing and the performance indicators from decreasing, which is manifested in decreased suction and increased noise. Thus, a good kitchen environment is created, the cleaning method is simple and efficient, great convenience is provided to users, and it is environmentally friendly and damageless, and effectively solves the problem that the inner wall of the volute of the existing range hood cannot be cleaned or is difficult to clean.

[0043] In some embodiments, the volute 110 may include an impeller 111 , an air inlet 112 , an air outlet 113 , and an oil leakage hole 114 .

[0044] The oil leakage hole 114 may be located at the lowest point of the volute 110 ; therefore, the oil and cleaning waste liquid on the inner wall of the volute may flow into the oil cup 120 below through the oil leakage hole 114 .

[0045] The air inlet 112 may be located at the center of the volute, so that when performing a cleaning procedure, the transport device 230 may transport the mixed liquid in the culture dish 220 to the air inlet 112 via the transport pipe 232 .

[0046] The impeller 111 may be located at the air inlet 112 inside the volute 110 . Therefore, when performing a cleaning procedure, the rotation of the impeller 111 may push the mixed liquid to the oil accumulation area inside the volute 110 .

[0047] Specifically, when the cleaning procedure is executed, the impeller rotates to push the mixed liquid transported to the inside of the volute 110 by the transport device 230 to the grease accumulation area inside the volute 110; the bubbles in the mixed liquid burst due to the kinetic energy generated by the rotation of the impeller and the impact generated by pushing to the grease accumulation area, and the energy generated during the bubble bursting process forms local high pressure and microjets, etc., which promote the process of peeling off the grease on the inner wall of the volute from the surface of the volute, thereby increasing the cleaning effect of the mixed liquid by increasing the contact area between the cleaning liquid and the oil.

[0048] The oil cup 120 is provided on the range hood body 10 and is used to collect oil stains generated during the use of the range hood body 10 and the cleaning process. The user can pour out the oil stains and cleaning waste liquid by removing the oil cup.

[0049] In some embodiments, a microorganism inactivation device (not shown in the drawings) may be provided in the oil cup to inactivate the biological activity of the cleaning microorganisms in the mixed liquid after cleaning.

[0050] The air outlet 113 may be located at the top of the range hood body 10 and is used to discharge the gas generated when the range hood body 10 is in use and the clean waste gas generated during the cleaning process.

[0051] The microorganism cleaning device 200 can be placed above the range hood body 10 via the baffle 130 .

[0052] The culture dish 220 may be located at the bottom of the microorganism cleaning device 200 and is provided with a leakage hole 231 at the bottom for allowing the mixed liquid in the culture dish 220 to flow into the transport device 230 through the leakage hole 231 when performing a cleaning procedure.

[0053] In some embodiments, the culture dish 220 may also be provided with an injection hole (not shown in the drawings), and the user may add culture fluid into the culture dish 220 through the injection hole.

[0054] In some embodiments, the mixed liquid in the culture dish 220 is composed of microorganisms, microbial products and culture liquid. The microbial products may include bubbles and active substances such as proteases, extracellular enzymes, organic acids, etc. The microorganisms in the culture dish 220 may be fermentation strains such as yeast and lactic acid bacteria.

[0055] In some embodiments, the microorganisms in culture dish 220 may also be a mixed strain of fermentative bacteria and oil-degrading microorganisms such as Pseudomonas, including archaea, bacteria, and fungi. It should be understood that those skilled in the art may, based on the principles of the present invention, employ other bacterial species to form other mixed strains, and the present invention is not limited thereto.

[0056] The monitoring device 210 may be located above the culture dish 220 , and together with the culture dish 220 , constitutes the microorganism cleaning device 200 ; the monitoring device 210 is used to monitor the conditions of the microorganisms and their products in the mixed liquid in the culture dish 220 and to control the microorganism cleaning device.

[0057] The sensor 211 and the processor 212 are located inside the monitoring device. The sensor 211 is used to collect culture data in the culture dish 220; the processor 212 is used to make corresponding cultivation decisions based on the data collected and obtained by the sensor 211.

[0058] Specifically, the sensor 211 is used to collect culture data in the culture dish 220, including: air pressure data, culture data of microorganisms in the mixed liquid and culture data of their products.

[0059] In some embodiments, the monitoring device 210 further includes a culture fluid regulating device (not shown in the drawings), which is used to regulate the culture environment in the culture dish 220 .

[0060] Specifically, the culture environment includes temperature, pH value, oxygen content, etc.

[0061] In some embodiments, the culture environment may further include other carbon sources such as glucose and sucrose, depending on the type of microorganisms cultured in the culture dish 220; other nitrogen sources such as inorganic nitrogen sources (such as ammonium salts, nitrates) or organic nitrogen sources; or certain trace elements such as Fe2O3 may be added according to the type of microorganisms and the characteristics of the oil pollution. + , Ca2 + Trace elements such as iodine and iodine have important effects on the growth and metabolic activities of microorganisms.

[0062] In some embodiments, depending on the type of microorganisms cultured in the culture dish 220, the culture environment may also include targeted changes in the dissolved oxygen content in the culture dish according to the type of microorganisms cultured in the culture dish 220, such as aerobic bacteria, anaerobic bacteria, or facultative anaerobic bacteria, such as increasing the dissolved oxygen content in the culture solution through aeration; or reducing the dissolved oxygen content through sealed culture, nitrogen purging, etc.

[0063] In some embodiments, the culture fluid regulating device is further configured to output a prompt message when the culture fluid is insufficient, reminding the user to replenish the culture fluid.

[0064] In some embodiments, the sensor 211 may include an air pressure sensor (not shown in the drawings) and an optical sensor (not shown in the drawings), specifically:

[0065] The air pressure sensor is used to obtain the air pressure conditions in the culture dish 220. The processor 212 can analyze the data obtained by the air pressure sensor based on a preset first mapping relationship to determine the generation of bubbles, one of the microbial products in the culture dish; after determining the generation of bubbles, the processor 212 uses the preset cleaning bubble standard to judge whether the bubbles generated by microorganisms in the mixed liquid meet the standard, and accordingly adjusts the environment in the culture dish 220 through the culture liquid adjustment device.

[0066] In other embodiments, when the bubble generation meets the cleaning bubble standard but the monitoring device 210 does not receive a cleaning instruction or the preset cleaning conditions are not met, the culture fluid regulating device adjusts the environment within the culture dish 220 to maintain the bubble generation in the mixed liquid at the current level.

[0067] The optical sensor is used to obtain the intensity value of the absorption peak in the culture dish 220. The processor 212 can obtain the content of active substances of the microbial species by comparing the preset values ​​of certain specific absorption peaks with the obtained absorption peak values; after obtaining the content of the active substance, the processor 212 determines whether the content of the active substance in the mixed liquid meets the standard of active substances for cleaning through a preset second mapping relationship, and accordingly adjusts the environment in the culture dish 220 through the culture liquid adjustment device.

[0068] In some embodiments, the processor 212 is configured to determine the generation status of the product according to the culture status data acquired by the sensor and determine whether the mixed liquid in the culture dish is in a ready state according to the generation status.

[0069] Specifically, when the mixed liquid meets the cleaning bubble standard and the cleaning active substance standard, the processor 212 determines that the mixed liquid in the culture dish 220 is in a ready state, and controls the quality of the mixed solution in the culture dish 220 through preset standards and real-time monitoring to ensure the quality of each cleaning.

[0070] In another embodiment, the optical sensor can be replaced with other optical sensors including fluorescence sensors, enzyme sensors, electrochemical sensors and the like, depending on the situation.

[0071] It should be clear that the optical sensor in the present invention can be regarded as any optical sensor that can achieve the advantages of non-invasiveness, rapid response and high selectivity, and the methods used by the optical sensor include but are not limited to optical absorption method, fluorescence spectroscopy, scattering spectroscopy, surface plasmon resonance (SPR) technology, optical resonant cavity technology and the like.

[0072] Reference Figure 1The transport device 230 is located inside the range hood body 10 and specifically includes a liquid leakage hole 231 and a transport pipe 232 ; one end of the transport pipe 232 is connected to the culture dish 220 , and the other end is connected to the volute air inlet 112 .

[0073] In some embodiments, a power plant is provided in the transport pipeline 232 .

[0074] In some embodiments, when the range hood body 10 performs a cleaning process, the transport device 230 transports the mixed liquid to the interior of the volute.

[0075] Specifically, the processor 212 controls the leakage hole 231 provided below the culture dish 220 to open, so that the mixed liquid flows into the transport pipe 232 , and the power device provided in the transport pipe 232 transports the mixed liquid through the air inlet 112 to the inside of the volute.

[0076] In some embodiments, the cleaning procedure can be executed only when the mixed liquid in the culture dish is in a ready state, a cleaning instruction is received, and the range hood body 10 meets the preset cleaning conditions.

[0077] Specifically, the preset cleaning condition may be when there is no abnormality in the range hood body 10 .

[0078] In some embodiments, the preset cleaning conditions of the range hood body 10 may be controlled by the user's settings;

[0079] Specifically, the user can set the execution time and execution duration of the cleaning program and the execution conditions from the control system of the range hood body 10, such as half an hour after the range hood stops absorbing oil fumes.

[0080] In some embodiments, the range hood cleaning instructions include the range hood cleaning instructions issued by the user in real time and the range hood cleaning instructions issued by the monitoring device 210 when the cleaning program set by the user is executed. In this way, it can avoid the situation where the user forgets to clean the oil stains in the volute inside the range hood for a long time, resulting in the accumulation of oil stains and the lack of cleaning.

[0081] According to an embodiment of the present invention, on the other hand, a range hood cleaning control method is provided, which is applicable to the range hood of any of the above embodiments. Figure 2 This is a flow chart of the steps of a range hood cleaning control method provided by an embodiment of the present invention. The cleaning control method includes the following steps:

[0082] Step 101: monitoring the production of the product in the culture dish through a monitoring device, controlling the culture environment in the culture dish according to the production of the product; and determining whether the mixed liquid in the culture dish is in a ready state according to the production of the product;

[0083] Specifically, this step is for the processor 212 in the monitoring device 210 to determine the generation status of the microbial products based on the culture status data in the culture dish 220 obtained by the sensor 211, and determine whether the mixed liquid is in a ready state based on the generation status. When the state of the mixed liquid is not ready, the processor will continue to monitor the generation status of the microbial products in the mixed liquid in the culture dish 220 until the mixed liquid in the culture dish is in a ready state.

[0084] Step 102: If the mixed liquid in the culture dish is in a ready state, the mixed liquid in the culture dish is transported to the volute by a transport device. The mixed liquid is diffused to the inner wall of the volute by the rotation of the impeller, and bubbles in the mixed liquid are exploded, thereby cleaning the oil stains on the inner wall of the volute;

[0085] Specifically, the cleaning process is as follows: the transport device 230 controls the leakage hole 231 located at the bottom of the culture dish 220 to open, and when the mixed liquid in the culture dish 220 flows into the transport pipe, the power device is started to pump the mixed liquid into the volute from the air inlet position through the transport pipe; the impeller pushes the mixed liquid transported by the transport device 230 to the grease accumulation area inside the volute 110 through rotation; the bubbles in the mixed liquid burst due to the kinetic energy generated by the rotation of the impeller and the impact generated by being pushed to the grease accumulation area, and the energy generated during the bubble bursting process forms local high pressure and micro jets, etc., which promote the process of peeling the grease on the inner wall of the volute from the volute surface, thereby increasing the cleaning effect of the mixed liquid by increasing the contact area between the cleaning liquid and the oil stains; when the cleaning is completed, the cleaning waste liquid mixed with fine grease molecules flows into the oil cup 120 below the range hood body 10 through the oil leakage hole 114 below the volute 110, and the clean waste gas is discharged from the air outlet 113 of the volute 110.

[0086] In one embodiment, the method may further include:

[0087] If the mixed liquid in the culture dish is not in a ready state, cleaning will be performed when the range hood body 10 meets the preset cleaning conditions and the mixed liquid in the culture dish is in a ready state.

[0088] Specifically, the preset cleaning conditions of the range hood body 10 can be whether it is in use and whether there is an abnormal state, and the state of the range hood cleaning device 200 can be whether there is an abnormal state; when the range hood body 10 is not in use and the range hood body 10 and the range hood cleaning device 200 are also in no abnormal state, the state of the range hood body 10 and the range hood cleaning device 200 is ready.

[0089] In some embodiments, when the range hood body 10 and the range hood cleaning device 200 are in an abnormal state, the monitoring device 210 outputs a reminder message to the user to remind the user of the possible situation.

[0090] In some embodiments, the reminder information output to the user by the monitoring device can be a voice broadcast, a text message sent to the user, a reminder sent through an APP, etc.; for example, when the impeller 111 of the volute 110 in the range hood body 10 is in an abnormal state, the monitoring device will send a reminder message to the user such as "The impeller state is abnormal, please contact a professional for inspection".

[0091] In some embodiments, receiving the range hood cleaning instruction includes:

[0092] Receive the range hood cleaning instruction issued by the user in real time, or receive the range hood cleaning instruction issued by the monitoring device 210 under the range hood cleaning scene preset by the user.

[0093] In some embodiments, the range hood cleaning scene preset by the user may be to clean the range hood body 10 a period of time after the range hood body 10 is used, and / or within a predetermined time period every day.

[0094] The range hood provided in this embodiment can not only start the range hood cleaning program by receiving the range hood cleaning instruction issued by the user in real time. For example, the range hood cleaning instruction issued by the user in real time includes instructions triggered by the user through buttons or voice instructions; it can also start the cleaning program regularly to prevent the user from forgetting to clean the range hood in time due to being busy. For example, it can be cleaned once every three months. Every time three months are reached, the monitoring device will issue a range hood cleaning instruction to clean the range hood.
