To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, the range hood is difficult to match different air discharge quantities in different cooking scenes, and is difficult to keep the kitchen cooking environment fresh and healthy. For a smoke exhaust system based on a common flue, under the condition that the starting rate of the range hood is low, the smoke exhaust resistance of the range hood is low, and the air exhaust is smooth; however, if the starting rate is high, the smoke discharge resistance of the bottom starting floor is high, and the smoke cannot be discharged well, so that the problem of unsmooth smoke discharge is caused. Especially, under a corresponding cooking scene, a user does not know the starting working condition of the current public flue system, and in order to balance the contradiction between the smoking effect and the noise of the range hood, the maximum range operating range hood cannot be directly started, so that the problems of oil smoke overflow and unsmooth smoke discharge are caused.
In order to solve the above problems, the following solutions may be adopted: (1) the smoke exhaust system sets a system air volume to ensure that each starting user has ideal single air exhaust volume under different working conditions; (2) the smoke exhaust system determines different effective exhaust air volumes according to the start-up rate, the effective air volume of the system is larger under the low start-up rate, and the effective exhaust air volume of the system is smaller under the high start-up rate; (3) and controlling the rotating speed of the range hood according to the relation between the rotating speed of the range hood and the actual air exhaust amount, thereby realizing the control of the effective air exhaust amount.
The solution for setting different air exhaust amounts under the single air exhaust amount setting or different working conditions has no big problem when being used by users under general conditions. However, the above solutions do not consider the cooking scenario, different air discharge amounts are likely to be required in different cooking scenarios, and the problems of insufficient or excessive air discharge may occur by adopting the above three solutions.
Based on the above, the embodiment of the invention provides a control method and device for a central range hood system and electronic equipment, and particularly provides a control method for the central range hood system to set different air volumes under different gears of a range hood.
In order to facilitate understanding of the present embodiment, a detailed description is first provided for a control method of a central range hood system disclosed in the embodiment of the present invention.
The first embodiment is as follows:
the embodiment of the invention provides a control method of a central range hood system, which is applied to a controller of the central range hood system, and is shown in a flow chart of the control method of the central range hood system shown in figure 1, wherein the control method of the central range hood system comprises the following steps:
step S102, acquiring parameters of a central range hood system; wherein, the parameter of central range hood system includes: the floor where each range hood is located, the specification of a common flue of the central range hood system, the total floor number of the central range hood system and the height of each floor.
The central range hood is a device which carries out communication networking on the range hoods on the same common flue and systematically coordinates and controls the actual exhaust volume of each range hood. Wherein, central range hood contains host computer, terminal machine. The main machine is a device which is arranged at the outlet of a common flue on the roof of the house and provides auxiliary power for the common flue; the terminal machine is a range hood or an integrated stove and other air exhaust devices comprising a fan, the operation frequency of the terminal machine can be controlled in a variable frequency mode, and the terminal machine is provided with a communication module and used for system networking.
The controller of the Central range hood system may be an electronic component such as an MCU (micro controller Unit), a CPU (Central Processing Unit), etc., and may be disposed in a control cabinet or an external Unit of the Central range hood system. The parameters of the central range hood system are used for calculating the pipeline exhaust resistance of each floor, and the range hoods of each floor can be networked in a communication mode so as to be convenient to control.
Step S104, acquiring the startup and shutdown signals and gear signals of the range hoods on each floor, and determining the effective exhaust volume of each target range hood based on the startup and shutdown signals and the gear signals; the target range hood represents the range hood in the starting state.
The power on/off signal of the range hood can represent whether the range hood is in a power on state or not, and the gear signal can represent the running gear of the range hood, wherein if the power on/off signal of the range hood represents that the range hood is in a power off state, the range hood possibly does not send the gear signal.
The target range hood of the embodiment represents the range hood in the starting state, and if a switch and a signal of one range hood represent that the range hood is in the starting state, the range hood can be called as the target range hood.
Generally, the effective exhaust air volume of the range hood is related to the gear of the range hood, so that the corresponding relation between the gear and the effective exhaust air volume can be preset, and the effective exhaust air volume of the target range hood is determined based on the corresponding relation. And, the culinary art scene of lampblack absorber can correspond with the gear, and the effective volume of airing exhaust of lampblack absorber corresponds with the gear of this lampblack absorber operation, and the culinary art scene of lampblack absorber can correspond with the effective volume of airing exhaust promptly.
And S106, determining the pipeline air exhaust resistance of each floor based on the effective air exhaust amount of each target range hood and the parameters of the central range hood system.
The pipeline exhaust resistance can be calculated based on the effective exhaust amount of each target range hood and the parameters of the central range hood system, specifically, the number of target range hoods in different gears can be counted firstly, and the pipeline exhaust resistance of the target range hoods in each starting floor when the effective exhaust amount is reached is calculated based on the number of the target range hoods in different gears, the parameters of the central range hood system and some other known parameters (such as the roughness of a common flue and the resistance coefficient of an indoor side exhaust pipeline).
And S108, determining a power demand difference value corresponding to the effective exhaust volume of each target range hood based on the preset power performance curve of each range hood and the pipeline exhaust resistance of each floor.
The resistance of the target range hood to be overcome under different effective exhaust air volumes can be calculated based on the preset power performance curves of the range hoods, and the difference between the pipeline exhaust air resistance and the resistance is calculated, namely the power demand difference corresponding to the effective exhaust air volumes of the target range hoods.
And step S110, determining the operating frequency of each target range hood based on the power demand difference.
The embodiment can determine the operating frequency of each target range hood according to the power demand difference. For example: if the power demand difference is high, the operating frequency of the target range hood needs to be increased, and if the power demand difference is low, the operating frequency of the target range hood needs to be reduced.
The embodiment of the invention provides a control method of a central range hood system, and for the range hood in the central range hood system, the proper operating frequency can be determined according to different working conditions and gears so as to be better suitable for different use scenes of the range hood, thereby controlling the range hood to effectively exhaust air.
Example two:
the present embodiment provides another control method for a central extractor hood system, which is implemented on the basis of the above embodiments, and with reference to a flowchart of another control method for a central extractor hood system shown in fig. 2, the control method for a central extractor hood system includes the following steps:
step S202, acquiring parameters of a central range hood system; wherein, the parameter of central range hood system includes: the floor where each range hood is located, the specification of a common flue of the central range hood system, the total floor number of the central range hood system and the height of each floor.
In the embodiment, firstly, parameter configuration can be carried out on the range hoods on all floors, and parameters for configuring the central range hood system comprise the floor position Fi where each range hood is located, the specification a multiplied by b of a common flue of the central range hood system, the total floor number N of the central range hood system and the floor height h of each floor; meanwhile, the range hoods on all floors are networked in a communication mode.
Step S204, acquiring the on-off signals and the gear signals of the range hoods on each floor, and determining the effective air exhaust volume of each target range hood based on the on-off signals and the gear signals; the target range hood represents the range hood in the starting state.
Specifically, whether each range hood is a target range hood can be determined based on the on-off signal; and determining the effective air exhausting amount of each target range hood based on the gear signal. Firstly, determining the range hood in the starting state as a target range hood based on the starting and stopping signal, and then determining the effective air exhaust volume of each target range hood according to the gear signal of the target range hood.
The corresponding relation between the gears of the range hoods and the effective air exhaust amount can be preset, and the gears of the target range hoods are determined based on the gear signals; and determining the effective air exhaust amount of each target range hood based on the gears and the corresponding relation of each target range hood.
For example, the range hood in this embodiment can have three gears, and each floor range hood broadcasts the on-off signal and the gear signal to the networking system in real time. The system presets three effective exhaust volumes of the range hood according to the gears of the range hood: q Z1 、Q Z2 And Q Z3 And is in one-to-one correspondence (Q) with X1 (low), X2 (middle) and X3 (high/quick stir-frying) gears of the range hood Z1 Corresponding to the air quantity of X1 gear, Q Z2 Corresponding to the air quantity of X2 gear, Q Z3 Corresponding to the air quantity of X3 level), and Q Z1 ＜Q Z2 ＜Q Z3 。
Step S206, determining the number of target range hoods of each gear based on the gear signals; and determining the pipeline air exhaust resistance of each floor based on the effective air exhaust amount of each target range hood, the number of the target range hoods at each gear, the parameters of the central range hood system, the preset roughness of the public flue and the preset resistance coefficient of the indoor side air exhaust pipeline.
In the embodiment, the number m of the target range hoods with the X1 gear in the central range hood system can be counted 1 Target range hood number m of X2 gear 2 Target range hood number m of X3 gear 3 And the floor position F of each target range hood in the public discharge flue system i Total floor number N, floor height h, common flue roughness k 1 And the specification of the common flue is a multiplied by b, and the resistance coefficient k of the indoor side exhaust duct 2 Calculating the pipeline exhaust resistance delta P of the target range hood of each starting floor when the target range hood reaches the set exhaust volume by the following formula i ＝f(Q z1 ，Q z2 ，Q z3 ，a，b，N，k 1 ，k 2 ，m 1 ，m 2 ，m 3 ，F i ，h)。
And S208, determining a power demand difference value corresponding to the effective exhaust volume of each target range hood based on the preset power performance curve of each range hood and the pipeline exhaust resistance of each floor.
The power performance curve of the range hood represents the corresponding resistance of the range hood under each operating frequency and each effective exhaust air volume. The resistance corresponding to the effective air exhaust amount of each target range hood can be determined based on the preset power performance curve of each range hood; and determining the power demand difference of each target range hood based on the resistance of each target range hood and the pipeline exhaust resistance of each floor.
Specifically, the operating frequency of each target range hood can be determined based on the gear of each target range hood; and determining the running frequency of each target range hood and the resistance corresponding to the effective air exhaust amount based on the preset power performance curve of each range hood.
Built-in lampblack absorber of lampblack absorber control panel each operating frequency R ni Dynamic performance curve f ni (P, Q), and the default operating frequency of the range hood in the X1/X2/X3 gear is R n1 /R n2 /R n3 And is calculated at Q from this frequency curve Z1 /Q Z2 /Q Z3 Resistance P capable of being overcome under exhaust air volume x1 /P x2 /P x3 。
Specifically, the power demand difference of each target range hood can be determined based on the resistance of each target range hood and the pipeline exhaust resistance of each floor by the following formula: p ci ＝ΔP i -P i (ii) a Wherein, P ci Is the power demand difference, delta P, of the ith target range hood i The air exhaust resistance, P, of the pipeline of the floor corresponding to the ith target range hood i Is the resistance of the ith target range hood.
For example, the power demand difference P of each starting range hood under the set air volume can be calculated by the following formula ci ＝ΔP i -P xy (wherein P is xy Is P x1 、P x2 、P x3 Specifically, determined by the range hood gear).
And step S210, determining the operating frequency of each target range hood based on the power demand difference.
Specifically, if the power demand difference is equal to a preset threshold value, the operating frequency of the target range hood remains unchanged; if the power demand difference is smaller than the threshold value, reducing the running frequency of the target range hood; if the power demand difference is greater than the threshold value and the power provided by the maximum operating frequency of the target range hood is greater than or equal to the pipeline air exhaust resistance of the floor corresponding to the target range hood, the operating frequency of the target range hood is increased to be the target operating frequency; wherein the target operating frequency is less than or equal to the maximum operating frequency.
Wherein, the threshold value can be 0, when P is ci When the frequency is 0, the operation frequency of the range hood is not adjusted; when P is ci When the frequency is less than 0, the operation frequency of the range hood is adjusted to be small according to each operationLower operating frequency R for the matching of the operating frequency power curve ni So that P is ci 0; when P is present ci When > 0, first judge R n max Under the operation frequency, when the air quantity is required, the power P provided by the range hood xy max Whether the power demand can be satisfied. If Δ P i ≤P xy max Then match the lower operating frequency R ni So that P is ci ＝0。
For the situation that the power demand difference is greater than the threshold value and the power provided by the maximum operating frequency of the target range hood is smaller than the pipeline exhaust resistance of the floor corresponding to the target range hood, the embodiment can process the situation in different modes according to whether the central range hood system has an outdoor host or not.
When the central range hood system does not comprise an outdoor host, if the power demand difference is greater than the threshold value and the power provided by the maximum operating frequency of the target range hood is smaller than the pipeline exhaust resistance of the corresponding floor of the target range hood, the operating frequency of the target range hood is increased to be the maximum operating frequency.
Referring to the schematic diagram of a central range hood system shown in fig. 3, the range hood is in stepless frequency conversion control, and can calculate the required exhaust power according to the exhaust resistance of the system, so as to match different operating frequencies of the range hood and meet the power requirement. The range hood is provided with a communication module and is used for carrying out system networking on the range hoods in the same common flue.
As shown in fig. 3, the central extractor hood system includes: a common flue, a fireproof check valve and a range hood (or an integrated stove). Wherein, the fire prevention check valve is installed at the joint of the common flue. The central range hood system shown in fig. 3 does not include an outdoor host, and cannot provide auxiliary power through the outdoor host, so when P is reached ci When > 0, if Δ P i ＞P xy max And then the range hood works under the maximum operation frequency.
When the central range hood system comprises the outdoor host, if the power demand difference is greater than the threshold value and the power provided by the maximum operating frequency of the target range hood is less than the pipeline air exhaust resistance of the corresponding floor of the target range hood, the outdoor host provides auxiliary power.
Referring to fig. 4, another schematic diagram of a central extractor hood system is shown, where the central extractor hood system includes an outdoor host and a terminal. The outdoor host comprises a power fan and a fan variable frequency control unit; the terminal machine is a range hood or an integrated stove and is provided with a communication module and a frequency conversion control module. The terminal machine and the host machine are in networking communication.
As shown in fig. 4, the central extractor hood system includes: outdoor host computer, public flue, fire prevention check valve, terminating machine. Wherein, the fire prevention check valve is installed at the public flue interface. The central range hood system shown in fig. 4 includes an outdoor main unit, which can provide auxiliary power, so that when P is reached ci When > 0, if Δ P i ＞P xy max And then the outdoor main machine needs to be started to provide auxiliary power.
