Description

Technical Field

[0001] The present application relates to the technical field of range hoods, and in particular to a range hood control method, a range hood control device, a range hood system and a storage medium. Background Art

[0002] In modern kitchen environments, range hoods play an extremely important role. They can effectively remove the fumes, odors and harmful gases generated during cooking, keep the kitchen air fresh, and reduce the potential harm of oil pollution to the kitchen environment and human health. However, with the use of range hoods, a large amount of oil pollution is easily accumulated inside.

[0003] Traditional range hood cleaning methods mostly rely on manual cleaning. Users need to regularly disassemble the range hood's filter, oil cup and other parts, soak and scrub them with detergent, and it is even more difficult to clean hard-to-reach parts such as the internal fan and air duct. This manual cleaning method not only consumes a lot of time and energy, but also due to the complex structure of the range hood, some hidden corners are often difficult to clean thoroughly, and residual oil will gradually accumulate, affecting the suction and performance of the range hood. In the long run, the accumulation of oil may also cause the range hood to have problems such as increased noise, increased vibration, and even malfunctions, shortening its service life and increasing maintenance costs.

[0004] At the same time, kitchen fumes contain a variety of harmful substances, such as grease, carcinogens such as benzopyrene, and dust particles. During the manual cleaning process, users will inevitably be exposed to these harmful substances, causing irritation and damage to the skin, respiratory tract, etc., and endangering their health.

[0005] Based on the many disadvantages of the above manual cleaning methods, the self-cleaning technology of range hoods came into being. The self-cleaning technology aims to reduce manual intervention through a series of automated designs and functions, effectively clean the oil stains inside the range hood, and maintain the good performance of the range hood. Early self-cleaning technology mainly focused on simple surface anti-fouling treatment, such as the use of special coatings to prevent oil stains from adhering to the surface of the range hood, but the cleaning effect on internal oil stains was limited.

[0006] With the continuous development of science and technology, the more common self-cleaning technologies currently include thermal dry cleaning, steam cleaning, water spraying and other methods. Thermal dry cleaning technology uses a heating device to soften the oil stains by heat, and then uses a high-speed rotating impeller to throw the softened oil stains off the fan surface; steam cleaning technology converts water into high-temperature and high-pressure steam, spraying it into the interior of the range hood to dissolve and flush the oil stains; water spray technology sprays water to specific parts through a nozzle, and cooperates with water flow guidance and collection devices to achieve the cleaning and discharge of oil stains. These self-cleaning technologies have improved the cleaning convenience and cleaning effect of range hoods to varying degrees, and can extend the maintenance cycle of range hoods to a certain extent, improve their use efficiency, and create a more convenient, healthy and efficient kitchen environment for users. However, the applicant found that the cleaning efficiency and cleaning effect of traditional fume systems are not good. Summary of the invention

[0017] In one embodiment, the steps are also included:

[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] The oil fume system control method of the present application is applied to an oil fume system 50, such as Figure 5 As shown, a fume system is provided, the fume system 50 includes a controller 52 , a water supply system 54 and N range hoods 56 ; the controller 52 is connected to the water supply system 54 and the range hoods 56 respectively; the water supply system 54 supplies water to the range hoods 56 .

[0044] In order to solve the problem of poor cleaning efficiency and cleaning effect of traditional range hood systems, in one embodiment, a range hood system control method is provided, and the range hood system control method is applied to the range hood system. It should be noted that the range hood system is generally applicable to large kitchens such as restaurant kitchens and hotel kitchens, and the range hood system also includes a water supply system and N range hoods, wherein the water supply system is used to supply water for self-cleaning of the range hoods. The N range hoods can operate independently.

[0045] like Figure 1 As shown, the oil fume system control method includes:

[0046] Step S110, monitoring the water supply pressure of the water supply system and the usage level of the range hood; the usage level is determined according to the accumulated operating time or the degree of oil accumulation of the range hood.

[0047] The controller of the oil fume system collects the water supply pressure of the water supply system in real time or periodically. Preferably, before the self-cleaning function of the range hood needs to be activated, the controller of the oil fume system collects the water supply pressure of the water supply system, for example, the previous minute, the previous two minutes, the previous thirty seconds, which can be set according to actual needs. The water supply pressure of the water supply system can be collected by a pressure sensor, a water pressure gauge or a digital pressure gauge. The usage level of the range hood is monitored from the last cleaning. Specifically, it can be characterized by the cumulative operating time or the degree of oil accumulation. For the cumulative operating time, a corresponding timer can be started for the cumulative operating time after the last cleaning. For the degree of oil accumulation, it can be monitored using equipment such as light reflection sensors, laser displacement sensors, capacitive sensors, resistive sensors, ultrasonic sensors or image recognition detection equipment.

[0048] Step S120, determining the batch of range hoods for self-cleaning and the number of range hoods corresponding to the same batch according to the water supply pressure and the usage level.

[0049] Since the self-cleaning of the range hood requires a lot of water, insufficient water supply will affect the cleaning efficiency and cleaning effect of the range hood. Therefore, during the cleaning process of the range hood, the water supply pressure of the range hood needs to be guaranteed. The self-cleaning function of range hoods of different brands and models has different requirements for water supply pressure, but generally requires the water pressure to be between 0.1MPa0.3MPa, that is, about 1 kgf / cm2 to 3 kgf / cm2. When the water pressure is lower than 0.1MPa, the detergent or hot water may not be effectively delivered to the parts that need to be cleaned due to the weak water flow, resulting in poor cleaning effect. If the water pressure is higher than 0.3MPa, it may cause greater pressure on the water pipes, nozzles and other components inside the range hood, increase the risk of component damage, and may also cause excessive water splashing, affecting the kitchen environment. During the self-cleaning process, the water pressure needs to remain relatively stable, and the fluctuation range should generally be controlled within ±0.05MPa of the set water pressure. Stable water pressure helps ensure that detergent or hot water can be sprayed continuously and evenly on the impeller, oil screen and other parts that need to be cleaned, thereby ensuring the consistency and reliability of the cleaning effect. If the water pressure fluctuates too much, sometimes the cleaning is not thorough, and sometimes the water pressure is too high and damages the parts.

[0050] The controller of the range hood system obtains the water pressure requirements of the range hood in advance, and calculates the number of range hoods that can be self-cleaned at the same time based on the water pressure requirements of the range hood and the collected water supply pressure. Specifically, after the water supply is divided, the water pressure of each branch is less than the water supply pressure. The more branches are divided, the smaller the water pressure of each branch. In order to improve the cleaning efficiency and ensure the cleaning effect, the number of range hoods is determined so that the water pressure of each branch at least meets the minimum requirements of the range hood. The greater the degree of use, the more serious the accumulation of oil stains, and the faster the cleaning is needed. Therefore, the cleaning order can be sorted based on the degree of use.

[0051] Specifically, in one example, the step of determining the order of self-cleaning of range hoods and the number of range hoods corresponding to the same order according to the water supply pressure and the degree of use includes the steps of: sorting the range hoods according to the degree of use from large to small; determining the batch of range hoods for self-cleaning and the number of range hoods corresponding to the same batch according to the water supply pressure, the minimum water pressure required for self-cleaning of the range hoods and the order of the range hoods. It should be noted that range hoods with a large degree of use are cleaned first, so that the range hoods in the range hood system are sorted. After sorting, the number of range hoods that can be self-cleaned at the same time in the same batch is determined according to the water supply pressure and the minimum water pressure required for self-cleaning of the range hoods, so that N range hoods are divided into M cleaning batches. It should be noted that M may be 1.

[0052] In one example, the step of determining the batch of range hoods for self-cleaning and the number of range hoods corresponding to the same batch based on the water supply pressure, the minimum water pressure required for range hood self-cleaning and the order of range hoods includes the following steps: in the order of range hoods, the range hoods are divided into batches from the first batch to all range hoods, based on the condition that the sum of the minimum water pressures of the maximum number of range hoods that can be satisfied by the water supply pressure in the same batch. The number of range hoods corresponding to the same batch is the maximum number of range hoods that can be satisfied by the water supply pressure, and the number of range hoods in the last batch may be less than the maximum number of range hoods that can be satisfied by the water supply pressure. For example, the total number of range hoods is 10, 4 are divided into the first batch, 4 are divided into the second batch, and 2 are divided into the third batch.

[0053] In order to improve the cleaning efficiency and save the cost of cleaning (for example, the cost of water resources and electricity resources), in one example, the oil fume system control method also includes the step of: if the usage level is less than the preset level, then the oil fume hoods corresponding to the usage level less than the preset level will not be sorted. The oil fume hood will not be self-cleaned until it has been used to a certain extent, so as to avoid excessively frequent cleaning and reduce the cleaning efficiency and cost of the overall oil fume system. Among them, the preset level can be set according to actual needs, and the preset level can be a preset cumulative operating time or a preset level of oil accumulation. When the usage level of the oil fume hood reaches the preset level, the oil fume hood will be added to the self-cleaning sorting in the current cleaning process, and the cleaning batches will be divided subsequently.

[0054] Step S130, based on the batches of the range hoods to be self-cleaned and the number of range hoods corresponding to the same batch, control the range hood to be self-cleaned. After the self-cleaning of the range hoods is sorted and divided into batches, the range hood is controlled to start self-cleaning based on the results of the division.

[0055] In one embodiment, the oil fume system further comprises a hot water system, wherein the hot water system is used to provide hot water for the self-cleaning of the oil fume hood, and the hot water system comprises a heating device, a water storage device, a control device and a water delivery device.

[0056] like Figure 2 As shown, the oil fume system control method includes the steps of:

[0057] Step S210, monitoring the water pressure of the water supply system and the use degree of the range hood; the use degree is determined according to the accumulated operation time of the range hood or the degree of grease accumulation. Step S210 is the same as the above step S110, and will not be repeated here.

[0058] Step S220, according to the water supply pressure and the usage level, determine the batch of range hoods to be self-cleaned and the number of range hoods corresponding to the same batch. Step S220 is the same as the aforementioned step S120 and will not be repeated here.

[0059] Step S230, determining the amount of hot water required for self-cleaning of the range hood according to the usage level of the range hood. In some cases, the accumulated oil stains in the range hood are difficult to clean, and hot water is needed to clean the oil stains in the range hood. Therefore, the amount of hot water is calculated and determined according to the usage level. The greater the usage level, the more accumulated oil stains there are, and the more hot water is needed. The required amount of hot water is determined by the usage level to avoid wasting electricity and water resources by using too much hot water.

[0060] Step S240, according to the number of range hoods corresponding to the same batch and the amount of hot water required for self-cleaning of the range hoods, the water inflow of the hot water system is determined, and the water inflow of the hot water system is controlled according to the water inflow. The required amounts of hot water of the range hoods in the same batch that are self-cleaned at the same time are added together to obtain the water inflow of the hot water system of the current batch, and the water inflow heating of the hot water system is controlled.

[0061] Step S250, based on the batch of range hoods for self-cleaning and the number of range hoods corresponding to the same batch, control the range hood to perform self-cleaning. In this example, step S250 is to use hot water for self-cleaning.

[0062] In one example, if Figure 3 As shown, the oil fume system control method also includes the steps of:

[0063] Step S310, check whether the range hood is in the shutdown state and within the preset self-cleaning period. The range hood cannot be cleaned during operation, and can only be cleaned when it is in the shutdown state. In addition, the preset self-cleaning period is set to ensure that there is enough time reserved for self-cleaning. For example, for a restaurant, cooking may be required at any time during the day, so it is not good to set the preset self-cleaning period during the day. The preset self-cleaning period can be set after the restaurant closes, for example, in the early morning. During the preset self-cleaning period, it is also necessary to ensure that the range hood is in the shutdown state.

[0064] Step S320: If the range hood is in a shutdown state and in a preset self-cleaning period, the water supply pressure of the water supply system and the use degree of the range hood are monitored. The water supply pressure of the water supply system and the use degree of the range hood are monitored only when the range hood is in a shutdown state and in a preset self-cleaning period.

[0065] Step S330, determining the batch of range hoods to be self-cleaned and the number of range hoods corresponding to the same batch according to the water supply pressure and the usage level. Step S330 is the same as the aforementioned step S120 and will not be described again here.

[0066] Step S340, based on the batch of range hoods to be self-cleaned and the number of range hoods corresponding to the same batch, control the range hood to be self-cleaned. Step S340 is the same as the aforementioned step S130, and will not be described again here.

[0067] In one example, if Figure 4 As shown, the oil fume system control method also includes the steps of:

[0068] Step S410, check whether the range hood is in the shutdown state and within the preset self-cleaning period. The range hood cannot be cleaned during operation, and can only be cleaned when it is in the shutdown state. In addition, the preset self-cleaning period is set to ensure that there is enough time reserved for self-cleaning. For example, for a restaurant, cooking may be required at any time during the day, so it is not good to set the preset self-cleaning period during the day. The preset self-cleaning period can be set after the restaurant closes, for example, in the early morning. During the preset self-cleaning period, it is also necessary to ensure that the range hood is in the shutdown state.

[0069] Step S420: If the range hood is in a shutdown state and in a preset self-cleaning period, the water supply pressure of the water supply system and the use degree of the range hood are monitored. The water supply pressure of the water supply system and the use degree of the range hood are monitored only when the range hood is in a shutdown state and in a preset self-cleaning period.

[0070] Step S430, according to the water supply pressure and the usage level, determine the batch of range hoods to be self-cleaned and the number of range hoods corresponding to the same batch. Step S430 is the same as the aforementioned step S120 and will not be repeated here.

[0071] Step S440, determining the amount of hot water required for self-cleaning of the range hood according to the usage level of the range hood. In some cases, the accumulated oil stains in the range hood are difficult to clean, and hot water is needed to clean the oil stains in the range hood. Therefore, the amount of hot water is calculated and determined according to the usage level. The greater the usage level, the more accumulated oil stains there are, and the more hot water is needed. The required amount of hot water is determined by the usage level to avoid wasting electricity and water resources by using too much hot water.

[0072] Step S450, according to the number of range hoods corresponding to the same batch and the amount of hot water required for self-cleaning of the range hoods, the water inflow of the hot water system is determined, and the water inflow of the hot water system is controlled according to the water inflow. The required amounts of hot water of the range hoods that are self-cleaning at the same time in the same batch are added together to obtain the water inflow of the hot water system of the current batch, and the water inflow heating of the hot water system is controlled.

[0073] Step S460, based on the batch of range hoods for self-cleaning and the number of range hoods corresponding to the same batch, control the range hood to perform self-cleaning. In this example, step S460 is to use hot water for self-cleaning.

[0074] In order to record the self-cleaning and let the user know the self-cleaning progress in time, in one example, based on the batch of range hoods that perform self-cleaning and the number of range hoods corresponding to the same batch, after controlling the range hood to perform self-cleaning, the following steps are included: recording the time point, time spent and water consumption of the range hood to complete self-cleaning; sending a reminder message to the remote device. The controller of the range hood system is connected to the remote device for communication and sends the self-cleaning information to the remote device corresponding to the user.

[0075] The oil fume system control method of the present application includes the following steps: monitoring the water supply pressure of the water supply system and the usage level of the oil hood; determining the usage level according to the accumulated operation time or the oil accumulation level of the oil hood; determining the batch of oil hoods for self-cleaning and the number of oil hoods corresponding to the same batch according to the water supply pressure and the usage level; controlling the oil hood for self-cleaning based on the batch of oil hoods for self-cleaning and the number of oil hoods corresponding to the same batch. The present application can determine the number of oil hoods that need to be cleaned at the same time according to the current water supply pressure and the usage level of the oil hood. Specifically, the greater the water supply pressure, the more oil hoods that are cleaned at the same time, and vice versa, the fewer oil hoods that are cleaned at the same time, thereby ensuring the cleaning efficiency and cleaning effect. In addition, the oil hoods with a greater usage level are given priority to avoid the problem of oil accumulation in the oil hood for a long time and subsequent difficulty in cleaning. At the same time, timely cleaning of the oil hood is conducive to ensuring the oil fume absorption effect of the oil hood.
