Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to a control method and device for a kitchen system, a kitchen system, and a computer-readable storage medium. Background Art

[0002] At present, as the problem of kitchen fume pollution has received increasing attention, users generally rely on natural ventilation to achieve kitchen air supply, so as to avoid the significant reduction in the fume extraction effect and the thermal efficiency of the stove when there is no air supply source. However, the use of window ventilation will cause a large amount of outdoor cold air or hot air to directly enter the kitchen space, thereby reducing the thermal comfort inside the kitchen. The use of door ventilation is likely to cause the fume to spread to other living spaces, thereby polluting the overall indoor environment. For this reason, the relevant technology proposes a kitchen air supply method, which independently introduces fresh air from the outside and directly sends it to both sides of the range hood without mixing with the airflow in other spaces; by controlling the air supply on both sides of the range hood to effectively protect the cooking hot smoke plume, the efficient capture performance of the range hood is guaranteed.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0004] Although the related technology controls the air supply volume to 50%-80% of the exhaust volume to maintain a micro-negative pressure state in the kitchen. However, it does not take into account the differences in exhaust and air supply requirements under different cooking modes, and the actual micro-negative pressure state is difficult to meet the needs of different cooking modes. For example, in the stir-fry mode, the oil fume may be difficult to exhaust due to insufficient exhaust volume; while in the steaming mode, energy consumption may be wasted due to redundant exhaust volume. On this basis, the related technology is prone to further excessive or insufficient air supply through fixed-ratio air supply, which in turn causes oil fume overflow or energy consumption surge. Therefore, the related technology is difficult to maintain a suitable micro-negative pressure state when facing different cooking modes and complex environmental conditions, and the user's actual cooking experience is poor.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0013] During the use of the kitchen system, the disclosed embodiment first determines the current cooking mode of the stove and matches the optimal exhaust volume required for the mode. Then the disclosed embodiment adjusts the current exhaust volume of the smoke exhaust fan accordingly, and then synchronously adjusts the corresponding air supply parameters of the air supply fan, so that it can adapt to the oil fume conditions corresponding to different cooking modes, and accurately maintain the micro-negative pressure state inside the kitchen by automatically adjusting the exhaust volume and the air supply volume.

[0025] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0026] The terms "first", "second", etc. in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0027] Unless otherwise stated, the term "plurality" means two or more.

[0028] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0029] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0030] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0031] Combination Figure 1 As shown, the embodiment of the present disclosure provides a kitchen system, including: a smoke exhaust fan 100 and an air supply fan 200. The kitchen system also includes a relatively independent exhaust duct and an air supply duct. The smoke exhaust fan 100 is arranged inside the exhaust duct to exhaust the air in the kitchen to the outside. The air supply fan 200 is arranged inside the air supply duct to lead the outdoor air into the kitchen.

[0032] By adopting the kitchen system provided in the embodiment of the present disclosure, the exhaust volume and supply air volume of the kitchen system can be adaptively adjusted by reasonably controlling the operating parameters of the smoke exhaust fan 100 and the supply air fan 200, thereby maintaining a stable micro-negative pressure state inside the kitchen, which is conducive to ensuring a higher oil fume capture efficiency and preventing the oil fume inside the kitchen from overflowing into other living spaces.

[0033] Optionally, the kitchen system further includes a stove 300. The stove 300 is disposed below the exhaust fan 100. In this way, the exhaust fan 100 and the stove 300 are disposed correspondingly up and down, so that the oil fume capture efficiency can be improved, so that the oil fume generated by the stove 300 can be quickly discharged to the outside.

[0034] Optionally, the kitchen system further includes an oil fume concentration detection sensor (not shown in the figure). The oil fume concentration detection sensor is arranged above the stove 300. In this way, the real-time oil fume concentration of the kitchen system can be regularly collected by the oil fume concentration detection sensor, so as to analyze the current oil fume working condition, and then reasonably optimize the exhaust volume and air supply volume of the kitchen system, which is conducive to more accurately controlling the micro-negative pressure state inside the kitchen to meet the actual needs of different cooking modes or complex environmental conditions.

[0035] Optionally, the kitchen system further includes a control device 400 for the kitchen system. The control device 400 of the kitchen system is electrically connected to the smoke exhaust fan 100 and the air supply fan 200, respectively. In this way, the embodiment of the present disclosure can execute a corresponding control method through the control device 400, and can reasonably control the operating parameters of the smoke exhaust fan 100 and the air supply fan 200, thereby achieving precise control of the micro-negative pressure state inside the kitchen, which is conducive to improving the actual cooking experience of users.

[0036] Based on the above kitchen system, combined with Figure 2 As shown, the embodiment of the present disclosure provides a control method for a kitchen system, comprising:

[0037] S101, when the kitchen system is turned on, the control device determines the current cooking mode of the stove.

[0038] S102, the control device adjusts the current exhaust volume of the smoke exhaust fan according to the current cooking mode of the stove.

[0039] S103, the control device adjusts the supply air parameters of the supply air fan according to the current exhaust air volume of the smoke exhaust fan.

[0040] Using the control method for the kitchen system provided by the embodiment of the present disclosure, during the use of the kitchen system, the current cooking mode of the stove is first determined, and the optimal exhaust volume required for the mode is matched. Then the embodiment of the present disclosure adjusts the current exhaust volume of the smoke exhaust fan accordingly, and then synchronously adjusts the corresponding air supply parameters of the air supply fan, so that it can adapt to the oil fume working conditions corresponding to different cooking modes, and accurately maintain the micro-negative pressure state inside the kitchen by automatically adjusting the exhaust volume and the air supply volume. As a result, the embodiment of the present disclosure can improve the oil fume capture efficiency and reduce the energy consumption of the fan, and can avoid the difficulty in exhausting oil fume in the stir-frying mode or the waste of energy in the steaming mode, so that the micro-negative pressure state of the kitchen accurately fits the requirements of different cooking modes, which is conducive to improving the actual cooking experience of users.

[0041] Optionally, the control device determines the current cooking mode of the stove, including: the control device obtains the real-time oil fume concentration of the kitchen system; the control device determines the current cooking mode of the stove according to the real-time oil fume concentration of the kitchen system.

[0042] In this way, the disclosed embodiment can identify the current cooking mode of the stove based on the real-time oil fume concentration, which is conducive to the subsequent dynamic adjustment of the exhaust volume to match the actual needs, thereby enhancing the adaptability of the kitchen system to different cooking scenarios.

[0043] Optionally, the control device determines the current cooking mode of the stove according to the real-time oil fume concentration of the kitchen system, including: when the real-time oil fume concentration of the kitchen system is greater than or equal to a first oil fume concentration, the control device determines that the current cooking mode of the stove is a stir-frying mode; or when the real-time oil fume concentration of the kitchen system is less than the first oil fume concentration and greater than or equal to a second oil fume concentration, the control device determines that the current cooking mode of the stove is a frying mode; or when the real-time oil fume concentration of the kitchen system is less than the second oil fume concentration, the control device determines that the current cooking mode of the stove is a steaming mode. Wherein, the first oil fume concentration is greater than the second oil fume concentration.

[0044] In this way, considering that there are significant differences in the oil fume characteristics corresponding to different cooking modes, the disclosed embodiment can accurately identify the current cooking mode in combination with the first oil fume concentration and the second oil fume concentration. When the real-time oil fume concentration exceeds the first oil fume concentration, it is determined that the stove is currently in the stir-frying mode. At this time, the oil fume load fluctuates violently and the instantaneous oil fume concentration is high. When the real-time oil fume concentration is between the first oil fume concentration and the second oil fume concentration, it is determined that the stove is currently in the frying mode. At this time, the oil fume generation is relatively continuous, and the oil fume load changes smoothly, and it is at a medium-high concentration level for a long time. When the real-time oil fume concentration is lower than the second oil fume concentration, it is determined that the stove is currently in the steaming mode, at which time water vapor is the main component and the oil fume concentration is extremely low.

[0045] Optionally, the control device adjusts the current exhaust air volume of the smoke exhaust fan according to the current cooking mode of the stove, including: when the current cooking mode of the stove is the stir-fry mode, the control device adjusts the current exhaust air volume of the smoke exhaust fan to the first exhaust air volume; or, when the current cooking mode of the stove is the frying mode, the control device adjusts the current exhaust air volume of the smoke exhaust fan to the second exhaust air volume; or, when the current cooking mode of the stove is the steaming mode, the control device adjusts the current exhaust air volume of the smoke exhaust fan to the third exhaust air volume. The first exhaust air volume is greater than the second exhaust air volume, and the second exhaust air volume is greater than the third exhaust air volume.

[0046] In this way, the disclosed embodiment can achieve refined exhaust control through hierarchical mapping of cooking mode and exhaust volume. In stir-fry mode, a relatively large first exhaust volume can be used to cope with instantaneous large oil fume load; in frying mode, a relatively moderate second exhaust volume can be used to balance capture efficiency and operating energy consumption; and in steaming mode, a relatively small third exhaust volume is used to save operating energy consumption and reduce noise. Therefore, the disclosed embodiment can realize dynamic adjustment of the current exhaust volume to enhance the adaptability of the kitchen system to different cooking scenarios, so as to better control the micro-negative pressure state inside the kitchen.

[0047] Based on the above kitchen system, combined with Figure 3 As shown, the embodiment of the present disclosure provides another control method for a kitchen system, comprising:

[0048] S201, when the kitchen system is turned on, the control device determines the current cooking mode of the stove.

[0049] S202, the control device adjusts the current exhaust volume of the smoke exhaust fan according to the current cooking mode of the stove.

[0050] S203, the control device determines the target adjustment frequency of the air supply fan according to the current cooking mode of the stove.

[0051] S204, the control device adjusts the supply air parameters of the supply air fan periodically according to the current exhaust air volume of the smoke exhaust fan according to the target adjustment frequency.

[0052] Using the control method for the kitchen system provided by the embodiment of the present disclosure, during the use of the kitchen system, the current cooking mode of the stove is first determined, and the optimal exhaust volume required for the mode is matched. Then the embodiment of the present disclosure adjusts the current exhaust volume of the smoke exhaust fan accordingly, and then synchronously adjusts the corresponding air supply parameters of the air supply fan, so that it can adapt to the oil fume working conditions corresponding to different cooking modes, and accurately maintain the micro-negative pressure state inside the kitchen by automatically adjusting the exhaust volume and the air supply volume. As a result, the embodiment of the present disclosure can improve the oil fume capture efficiency and reduce the energy consumption of the fan, and can avoid the difficulty in exhausting oil fume in the stir-frying mode or the waste of energy in the steaming mode, so that the micro-negative pressure state of the kitchen accurately fits the requirements of different cooking modes, which is conducive to improving the actual cooking experience of users. In addition, the disclosed embodiments can reasonably optimize the air supply control strategy based on the oil fume characteristics corresponding to different cooking modes, and regularly adjust the air supply parameters by adopting a target adjustment frequency that matches the current cooking mode, thereby improving the real-time and stability of the air supply control, so as to avoid the low-frequency adjustment in the stir-frying mode being unable to quickly respond to the drastic fluctuations in oil fume or the high-frequency adjustment in the steaming mode generating more redundant controls, which is beneficial to enhancing the adaptability of the kitchen system to different cooking scenarios.

[0053] Optionally, the control device determines the target adjustment frequency of the air supply fan according to the current cooking mode of the stove, including: when the current cooking mode of the stove is the stir-fry mode, the control device determines the target adjustment frequency of the air supply fan to be the first adjustment frequency; or when the current cooking mode of the stove is the frying mode, the control device determines the target adjustment frequency of the air supply fan to be the second adjustment frequency; or when the current cooking mode of the stove is the steaming mode, the control device determines the target adjustment frequency of the air supply fan to be the third adjustment frequency. The first adjustment frequency is greater than the second adjustment frequency, and the second adjustment frequency is greater than the third adjustment frequency.

[0054] In this way, the disclosed embodiment can realize refined air supply control through the dynamic association between the cooking mode and the air supply adjustment frequency. In the stir-fry mode, a relatively high-frequency first adjustment frequency can be used to ensure a rapid response to instantaneous oil smoke fluctuations; in the frying mode, a relatively medium-frequency second adjustment frequency can be used to maintain a stable micro-negative pressure state; and in the steaming mode, a relatively low-frequency third adjustment frequency is used to reduce control energy consumption. Therefore, the disclosed embodiment can realize dynamic adjustment of the air supply adjustment frequency to enhance the adaptability of the kitchen system to different cooking scenarios, which is conducive to optimizing the real-time and stability of air supply control.

[0055] Based on the above kitchen system, combined with Figure 4 As shown, the embodiment of the present disclosure provides another control method for a kitchen system, comprising:

[0056] S301, when the kitchen system is turned on, the control device determines the current cooking mode of the stove.

[0057] S302, the control device adjusts the current exhaust volume of the smoke exhaust fan according to the current cooking mode of the stove.

[0058] S303, the control device determines the target micro-negative pressure value of the kitchen system according to the current exhaust volume of the smoke exhaust fan.

[0059] S304, the control device adjusts the air supply parameters of the air supply fan according to the target slight negative pressure value of the kitchen system, so that the real-time negative pressure value of the kitchen system approaches the target slight negative pressure value.

[0060] Using the control method for the kitchen system provided by the embodiment of the present disclosure, during the use of the kitchen system, the current cooking mode of the stove is first determined, the optimal exhaust volume required for the mode is matched, and the optimal target micro-negative pressure value of the kitchen system corresponding to it is matched. Then the embodiment of the present disclosure adjusts the current exhaust volume of the exhaust fan accordingly, and then synchronously adjusts the corresponding air supply parameters of the air supply fan, so that it can adapt to the oil fume working conditions corresponding to different cooking modes, so that the real-time negative pressure value of the kitchen system gradually approaches the target micro-negative pressure value, thereby accurately maintaining the micro-negative pressure state inside the kitchen. Therefore, the embodiment of the present disclosure can improve the oil fume capture efficiency and reduce the energy consumption of the fan on the one hand, which can avoid the oil fume being difficult to exhaust in the stir-frying mode or the energy waste caused in the steaming mode, so that the micro-negative pressure state of the kitchen is accurately matched to the requirements of different cooking modes. On the other hand, it can synergistically improve the oil fume capture efficiency and the anti-overflow effect under different working conditions, which can avoid the energy consumption surge when the kitchen system has a high exhaust volume or the oil fume escapes when the exhaust volume is low, so that the kitchen system is always maintained in the optimal micro-negative pressure state, which is conducive to improving the actual cooking experience of users.

[0061] Optionally, the target micro-negative pressure value range is [-20Pa, 0Pa], and the specific value can be determined by constructing a preset three-dimensional correspondence between the exhaust volume, the negative pressure value and the performance parameter. The range of the target micro-negative pressure value can also be adjusted according to the actual needs of the user for the performance index, and its effective range can also be appropriately expanded or reduced.

[0062] Optionally, the control device determines the target micro-negative pressure value of the kitchen system based on the current exhaust volume of the smoke exhaust fan, including: the control device obtains a preset three-dimensional correspondence between the exhaust volume, the negative pressure value and the performance parameter; wherein the first dimension stores multiple discrete exhaust volumes, the second dimension stores multiple discrete negative pressure values, and the third dimension stores performance parameter values ​​corresponding to multiple combinations of exhaust volume and negative pressure values; the control device obtains one or more candidate negative pressure values ​​corresponding to the current exhaust volume of the smoke exhaust fan in the preset three-dimensional correspondence according to preset performance compliance conditions; wherein the performance parameter values ​​corresponding to the combination of the current exhaust volume and the candidate negative pressure values ​​meet the preset performance compliance conditions; the control device determines the minimum value among the candidate negative pressure values ​​as the target micro-negative pressure value.

[0063] In this way, the embodiment of the present disclosure can pre-construct a preset three-dimensional correspondence between the exhaust volume, the negative pressure value and the performance parameters, and select one or more candidate negative pressure values ​​that meet the preset performance standards under the current exhaust volume in combination with the performance index requirements, thereby avoiding the problem of inefficient capture or energy consumption surge caused by the large deviation of the negative pressure value inside the kitchen under complex working conditions. Then the embodiment of the present disclosure preferentially selects the smallest candidate negative pressure value as the target micro-negative pressure value, and the corresponding negative pressure environment inside the kitchen is more significant, which can effectively suppress the escape of oil smoke to other living spaces, and at the same time can also reduce the redundant amount of air supply, which is conducive to further improving the energy-saving effect. Therefore, the embodiment of the present disclosure can realize the dynamic optimization matching of the current exhaust volume and the target micro-negative pressure value, so that the kitchen system is always maintained in the optimal micro-negative pressure state, so as to simultaneously meet multiple requirements such as efficient capture, low energy consumption and overflow prevention, which is conducive to better improving the actual cooking experience of users.

[0064] Optionally, the preset three-dimensional correspondence includes one or more correspondences of exhaust volume, negative pressure value and performance parameter. For example, Table 1 shows a correspondence of exhaust volume, negative pressure value and capture efficiency, as shown in the following table:

[0065] Table 1

[0066]

[0067]

[0068] Among them, A0~A15 means the exhaust volume is 480m 3 / h, the capture efficiency values ​​corresponding to different negative pressure values, B0~B15 represent the exhaust volume of 720m 3 / h, the capture efficiency values ​​corresponding to different negative pressure values, C0~C15 represent the exhaust volume of 960m 3 / h, the capture efficiency values ​​corresponding to different negative pressure values ​​are respectively, and the above capture efficiency values ​​can be measured through experiments.

[0069] For example, Table 2 shows a corresponding relationship between exhaust volume, negative pressure value and operating energy consumption, as shown in the following table:

[0070] Table 2

[0071]

[0072] Among them, X0~X15 represents the exhaust volume of 480m 3 / h, the operating energy consumption values ​​corresponding to different negative pressure values, Y0~Y15 represent the exhaust volume of 720m 3 / h, the operating energy consumption values ​​corresponding to different negative pressure values, Z0~Z15 represent the exhaust volume of 960m 3 / h, the operating energy consumption values ​​corresponding to different negative pressure values ​​are obtained through experiments.

[0073] Optionally, the control device determines whether the performance parameter value corresponding to the current exhaust volume and the candidate negative pressure value combination meets the preset performance compliance condition in the following manner, including: when the capture efficiency value corresponding to the current exhaust volume and the candidate negative pressure value combination is greater than or equal to the capture efficiency threshold, the control device determines that the preset performance compliance condition is met. In this way, the embodiment of the present disclosure can determine whether the preset performance compliance condition is met by the capture efficiency threshold. Under the current exhaust volume, if the capture efficiency value corresponding to any negative pressure value is greater than or equal to the capture efficiency threshold, it can be determined as a candidate negative pressure value, and the kitchen system can meet the efficient capture requirements.

[0074] and / or,

[0075] Optionally, the control device determines whether the performance parameter value corresponding to the current exhaust volume and the candidate negative pressure value combination meets the preset performance compliance condition in the following manner, including: when the operating energy consumption value corresponding to the current exhaust volume and the candidate negative pressure value combination is less than or equal to the operating energy consumption threshold, the control device determines that the preset performance compliance condition is met. In this way, the embodiment of the present disclosure can determine whether the preset performance compliance condition is met by the operating energy consumption threshold. Under the current exhaust volume, if the operating energy consumption value corresponding to any negative pressure value is less than or equal to the operating energy consumption threshold, it can be determined as a candidate negative pressure value, and the kitchen system can meet the low energy consumption requirement.

[0076] Optionally, the control device adjusts the air supply parameters of the air supply fan according to the target micro-negative pressure value of the kitchen system so that the real-time negative pressure value of the kitchen system approaches the target micro-negative pressure value, including: when the real-time negative pressure value of the kitchen system is less than the target micro-negative pressure value, the control device increases the operating power and / or supply air volume of the air supply fan; or, when the real-time negative pressure value of the kitchen system is greater than the target micro-negative pressure value, the control device reduces the operating power and / or supply air volume of the air supply fan.

[0077] In this way, the embodiment of the present disclosure can reasonably adjust the air supply parameters based on the dynamic deviation between the real-time negative pressure value and the target micro-negative pressure value of the kitchen system to ensure that the kitchen system always maintains the optimal micro-negative pressure state. When the real-time negative pressure value is less than the target micro-negative pressure value, it indicates that the absolute value of the negative pressure inside the kitchen is large. At this time, the oil fume capture efficiency is low and it is easy to cause energy waste. Therefore, the embodiment of the present disclosure can appropriately increase the operating power and / or air supply volume of the air supply fan to quickly increase the real-time negative pressure value to near the target micro-negative pressure value, so as to facilitate the kitchen system to restore the optimal micro-negative pressure state to meet the requirements of efficient capture and low energy consumption. When the real-time negative pressure value is greater than the target micro-negative pressure value, it indicates that the absolute value of the negative pressure inside the kitchen is small. At this time, it is easy to form a positive pressure environment inside the kitchen and cause oil fume overflow. Therefore, the embodiment of the present disclosure can appropriately reduce the operating power and / or air supply volume of the air supply fan to quickly reduce the real-time negative pressure value to near the target micro-negative pressure value, so as to facilitate the kitchen system to restore the optimal micro-negative pressure state to meet the requirements of efficient capture and anti-overflow.

[0078] Optionally, the control device may use a PID (Proportional Integral Derivative) algorithm to increase or decrease the operating power and / or the supply air volume of the supply air fan. In this way, the disclosed embodiment can accurately adjust the supply air parameters of the supply air fan, appropriately increase the operating power and / or the supply air volume of the supply air fan when the absolute value of the kitchen negative pressure is large, and appropriately reduce the operating power and / or the supply air volume of the supply air fan when the absolute value of the kitchen negative pressure is small, so that the real-time negative pressure value of the kitchen system can be kept near the target micro-negative pressure value, so that the kitchen system is always maintained in an optimal micro-negative pressure state.

[0079] Optionally, combined Figure 5 As shown, the embodiment of the present disclosure provides a cloud diagram of oil fume concentration corresponding to different negative pressure values ​​of a kitchen system under a preset exhaust volume. Figure 5 -a indicates that the real-time negative pressure value of the kitchen system under the preset exhaust volume is much smaller than the oil fume concentration cloud corresponding to the target micro-negative pressure value; Figure 5 -b indicates the smoke concentration cloud map corresponding to the kitchen system's real-time negative pressure value being slightly less than the target micro-negative pressure value under the preset exhaust volume; Figure 5 -c indicates the smoke concentration cloud map corresponding to the target micro-negative pressure value when the real-time negative pressure value of the kitchen system is equal to the preset exhaust volume; Figure 5 -d indicates that the real-time negative pressure value of the kitchen system under the preset exhaust volume is slightly greater than the oil fume concentration cloud map corresponding to the target micro-negative pressure value.

[0080] Specifically, in some embodiments, the kitchen doors and windows are closed, and the smoke exhaust fan is controlled to operate according to the preset exhaust volume, and the air supply fan is controlled to stop operating. Since there is no air supply source, as the kitchen continues to exhaust air to the outside, the real-time negative pressure value of the kitchen system will become lower and lower, and eventually it will be far less than the target micro-negative pressure value. Figure 5 -a, at this time, a high negative pressure state is formed inside the kitchen, and the actual oil fume capture efficiency of the smoke exhaust fan is extremely low, which makes it difficult to discharge the oil fume, and the oil fume concentration in various places inside the kitchen is at a high level.

[0081] Specifically, in some other embodiments, the kitchen doors and windows are closed, and the smoke exhaust fan is controlled to operate at a preset exhaust volume, and the make-up air fan is controlled to operate at a smaller make-up air volume. Since the air volume difference between the smoke exhaust fan and the make-up air fan is relatively large, the real-time negative pressure value of the kitchen system is relatively small, causing it to be slightly smaller than the target micro-negative pressure value. Figure 5 -b, at this time, a negative pressure state is formed inside the kitchen, and the actual oil fume capture efficiency of the smoke exhaust fan fails to meet the high-efficiency capture requirements, causing part of the oil fume to escape to the upper space of the kitchen. At this time, the oil fume concentration in the upper space of the kitchen is slightly higher.

[0082] Specifically, in other embodiments, the kitchen doors and windows are closed, and the smoke exhaust fan is controlled to operate according to the preset exhaust volume, and the make-up air fan is controlled to operate with the optimal make-up air volume. By accurately controlling the appropriate air volume difference between the smoke exhaust fan and the make-up air fan, the real-time negative pressure value of the kitchen system can be stabilized near the target micro-negative pressure value. Figure 5 -c, at this time, the best micro-negative pressure state is formed inside the kitchen, and the actual oil fume capture efficiency of the smoke exhaust fan is relatively high, which can meet the requirements of high-efficiency capture. The oil fume generated by the stove is effectively exhausted to the outside through the smoke exhaust fan, thereby achieving the goal of meeting the oil fume concentration standards in various parts of the kitchen.

[0083] Specifically, in other embodiments, the kitchen doors and windows are closed, and the smoke exhaust fan is controlled to operate at a preset exhaust volume, and the make-up air fan is controlled to operate at a make-up air volume equivalent to the preset exhaust volume. Since there is basically no air volume difference between the smoke exhaust fan and the make-up air fan, the real-time negative pressure value of the kitchen system approaches 0 and is slightly greater than the target micro-negative pressure value. Figure 5 -d, a positive pressure state is easily formed inside the kitchen, causing some oil smoke to spread to living rooms, bedrooms and other living spaces. The actual oil smoke capture efficiency of the exhaust fan is reduced. At this time, the oil fume concentration in some parts of the kitchen is slightly higher, and the oil fume overflow phenomenon becomes more obvious.

[0084] Based on the above kitchen system, combined with Figure 6 As shown, the embodiment of the present disclosure provides another control method for a kitchen system, comprising:

[0085] S401, when the kitchen system is turned on, the control device determines the current cooking mode of the stove.

[0086] S402, the control device adjusts the current exhaust volume of the smoke exhaust fan according to the current cooking mode of the stove.

[0087] S403, the control device determines the target operating power of the smoke exhaust fan according to the current exhaust volume of the smoke exhaust fan.

[0088] S404, the control device adjusts the supply air parameters of the supply air fan according to the target operating power of the smoke exhaust fan, so that the real-time operating power of the smoke exhaust fan approaches the target operating power.

[0089] By adopting the control method for the kitchen system provided by the embodiment of the present disclosure, during the use of the kitchen system, the current cooking mode of the stove is first determined, the optimal exhaust volume required for the mode is matched, and the optimal target operating power of the corresponding exhaust fan is matched. Then the embodiment of the present disclosure adjusts the current exhaust volume of the exhaust fan accordingly, and then synchronously adjusts the corresponding air supply parameters of the air supply fan, so that it can adapt to the oil fume working conditions corresponding to different cooking modes, so that the real-time operating power of the exhaust fan gradually approaches the target operating power, thereby realizing accurate control of the optimal working state of the exhaust fan. Therefore, the embodiment of the present disclosure can improve the oil fume capture efficiency and reduce the fan energy consumption on the one hand, and can avoid the oil fume in the stir-frying mode being difficult to exhaust or the energy waste in the steaming mode, so that the micro-negative pressure state of the kitchen can accurately fit the requirements of different cooking modes. On the other hand, it can synergistically improve the oil fume capture efficiency and the anti-overflow effect under different working conditions, and can avoid the energy consumption surge when the kitchen system has a high exhaust volume or the oil fume escapes when the exhaust volume is low, so that the kitchen system is always maintained in the optimal micro-negative pressure state, which is conducive to improving the actual cooking experience of users.

[0090] Optionally, the control device determines the target operating power of the smoke exhaust fan based on the current exhaust volume of the smoke exhaust fan, including: the control device determines the benchmark operating power of the smoke exhaust fan based on the current exhaust volume of the smoke exhaust fan; the control device corrects the benchmark operating power of the smoke exhaust fan based on the target micro-negative pressure value of the kitchen system to obtain the target operating power of the smoke exhaust fan.

[0091] In this way, the embodiment of the present disclosure can determine the reference operating power that matches the current exhaust volume of the smoke exhaust fan based on the correspondence between the exhaust volume and the operating power under the daily working conditions of the kitchen. Then the embodiment of the present disclosure considers the actual impact of the micro-negative pressure state on the exhaust volume. When the kitchen is in a negative pressure environment, the exhaust volume of the smoke exhaust fan will produce a certain loss. Based on this, the current exhaust volume can be kept stable by slightly increasing the operating power of the smoke exhaust fan. On this basis, the embodiment of the present disclosure can establish a correlation between the negative pressure value inside the kitchen and the correction value or correction ratio of the operating power of the smoke exhaust fan. Therefore, the embodiment of the present disclosure can match the corresponding power correction coefficient in combination with the target micro-negative pressure value determined by the kitchen system, and then obtain the target operating power of the smoke exhaust fan corresponding to the optimal micro-negative pressure state of the kitchen based on the reference operating power and the power correction coefficient, which is conducive to accurately maintaining the optimal micro-negative pressure state inside the kitchen according to the target operating power.

[0092] Optionally, the control device adjusts the supply air parameters of the supply air fan according to the target operating power of the smoke exhaust fan so that the real-time operating power of the smoke exhaust fan approaches the target operating power, including: when the real-time operating power of the smoke exhaust fan is greater than the target operating power, the control device increases the operating power and / or the supply air volume of the supply air fan; or, when the real-time operating power of the smoke exhaust fan is less than the target operating power, the control device reduces the operating power and / or the supply air volume of the supply air fan.

[0093] In this way, the disclosed embodiment can reasonably adjust the air supply parameters based on the dynamic deviation between the real-time operating power and the target operating power of the smoke exhaust fan, so as to ensure that the smoke exhaust fan operates at the optimal target operating power for a long time, thereby ensuring that the kitchen system always maintains the optimal micro-negative pressure state. When the real-time operating power of the smoke exhaust fan is greater than the target operating power, it indicates that the absolute value of the negative pressure inside the kitchen is large, and the exhaust volume is greatly affected by the negative pressure. At this time, the oil fume capture efficiency is low and energy waste is easy to occur. Therefore, the disclosed embodiment can appropriately increase the operating power and / or the air supply volume of the air supply fan so that the kitchen system can restore the optimal micro-negative pressure state, thereby facilitating the real-time operating power to quickly reduce to near the target operating power to meet the requirements of efficient capture and low energy consumption. When the real-time operating power is less than the target operating power, it indicates that the absolute value of the negative pressure inside the kitchen is small. At this time, a positive pressure environment is easily formed inside the kitchen, thereby causing oil fume to overflow, and the exhaust volume may overflow due to the positive pressure. Therefore, the embodiments of the present disclosure can appropriately reduce the operating power and / or air volume of the air supply fan so that the kitchen system can restore the optimal micro-negative pressure state, which is conducive to quickly increasing the real-time operating power to near the target operating power to meet the needs of efficient capture and overflow prevention.

[0094] Optionally, the control device may use a PID (Proportional Integral Derivative) algorithm to increase or decrease the operating power and / or the supply air volume of the supply air fan. In this way, the disclosed embodiment can accurately adjust the supply air parameters of the supply air fan, appropriately increase the operating power and / or the supply air volume of the supply air fan when the real-time operating power of the smoke exhaust fan is too large, and appropriately reduce the operating power and / or the supply air volume of the supply air fan when the real-time operating power of the smoke exhaust fan is too small, so that the kitchen system can be maintained in an optimal micro-negative pressure state, so that the real-time operating power of the smoke exhaust fan is kept near the target operating power.

[0095] Optionally, when the kitchen system is turned on, it also includes: the control device obtains the real-time oil fume concentration of the kitchen system; when the real-time oil fume concentration of the kitchen system is greater than or equal to the preset oil fume concentration, the control device starts the smoke exhaust fan.

[0096] Thus, during the use of the kitchen system, the embodiment of the present disclosure first detects the real-time oil fume concentration of the kitchen system to determine whether it is necessary to start the exhaust fan, thereby avoiding energy waste caused by the ineffective operation of the exhaust fan under smokeless or low smoke conditions. When it is detected that the real-time oil fume concentration of the kitchen system is greater than or equal to the preset oil fume concentration, the embodiment of the present disclosure can immediately start the exhaust fan to discharge the generated oil fume to the outside in a timely manner, thereby ensuring the user's cooking experience.
