[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.

[0029] Considering that single-unit oil drainage presses, single-unit make-up air fans, and single-unit fresh air fans are commonly used in the existing market, with independent control and inability to coordinate and match the actual air exhaust volume requirements of the system, resulting in low smoke exhaust efficiency and thus reducing the user experience; based on this, a method, device, and electronic device for air volume adjustment provided by an embodiment of the present invention can automatically adjust the valves of the flow distribution valve and the smoke exhaust and make-up air valve, or the valves of the flow distribution valve and the fresh air inlet valve, effectively discharge kitchen fumes, and further improve the user experience.

[0030] For ease of understanding of this embodiment, the method for air volume adjustment provided by an embodiment of the present invention will be introduced in detail below. Among them, the execution entity is the control host of the central range hood system. Figure 1 A schematic structural diagram of a central range hood system is shown, as Figure 1 shown, the central range hood system includes a control host 100, and terminal machines 101, smoke exhaust and make-up air valves 102, and fresh air inlet valves 103 on each floor that are communicatively connected to the control host 100. Each terminal machine 101 is connected to a common flue ( Figure 1 not shown in the figure) through a connecting pipe ( Figure 1 not shown in the figure). A flow distribution valve 104 is provided on the connecting pipe, and the flow distribution valve 104 is communicatively connected to the control host 100. Figure 1 Only 2 terminal machines 101 are shown in the figure. Since only one terminal machine 101 is configured on each floor, the number of flow distribution valves 104 is also 2. In actual use, the number of terminal machines 101 connected to the control host 100 can be set according to actual needs and is not limited herein.

[0031] In actual use, the smoke exhaust and make-up air valve and the fresh air inlet valve can be installed at any position in the room where the terminal machine is located, and the number of smoke exhaust and make-up air valves and fresh air inlet valves can be arranged in multiple numbers according to actual needs. The number of smoke exhaust and make-up air valves and fresh air inlet valves in the same room is not limited herein. Figure 1 In the figure, it is shown by taking one smoke exhaust and make-up air valve and one fresh air inlet valve on each floor as an example. Therefore, the number of smoke exhaust and make-up air valves and fresh air inlet valves is also 2 each.

[0032] For ease of understanding, Figure 2 Another schematic structural diagram of a central range hood system is shown. Figure 2 Taking the 3 floors shown in the figure as an example, one terminal machine 101 is installed on each floor. The 3 terminal machines are respectively connected to the common flue 201 through connecting pipes 200. Moreover, the flow distribution valves 104 provided on each connecting pipe and each terminal machine 101 are communicatively connected to the control host 100. And one smoke exhaust and make-up air valve 102 and one fresh air inlet valve 103 are installed in the room where each floor terminal machine is located.

[0033] Based on the above control host, an embodiment of the present invention provides a method for air volume regulation. Figure 3 The flowchart of a method for air volume regulation is shown, as Figure 3 shown. The method includes the following steps:

[0034] Step S302, obtaining the working condition information sent by the target terminal machine when it is powered on;

[0035] Among them, the working condition information carries the power-on signal of the target terminal machine and the required air intake volume. The required air intake volume is obtained by the gear information sent by the control panel of the target terminal machine and calculated based on the gear information. The power-on signal is an oil fume exhaust power-on signal or a fresh air power-on signal.

[0036] A control panel is provided on each terminal machine. The above control panel can be a touch panel, a mechanical button panel, an infrared control panel, a mobile terminal panel, etc. And, on the control panel, there are set the start-up gear keys of the smoke exhaust air supply valve corresponding to the smoke exhaust air supply fan and the start-up gear keys of the fresh air inlet valve corresponding to the fresh air inlet fan. It can be understood that when the user operates the start-up gear keys, the smoke exhaust air supply valve or the fresh air inlet valve opens. There are also set gear keys for controlling the air intake volume on the control panel. The target terminal machine when it is powered on can obtain the corresponding gear information by the user controlling the gear keys, and further can query the required air intake volume corresponding to the gear information in the air intake query table. Among them, the air intake query table stores the corresponding relationship between the gear information and the air intake volume.

[0037] Since opening the smoke exhaust air supply valve and the fresh air inlet valve at the same time seriously affects the discharge of oil fume, therefore, in this embodiment, it is stipulated that when the smoke exhaust air supply valve is opened, the fresh air inlet valve is closed, and when the fresh air inlet valve is opened, the smoke exhaust air supply valve is closed. So, the above power-on signal can only be an oil fume exhaust power-on signal or a fresh air power-on signal.

[0038] Step S304, determining the first host power of the control host according to the power-on signal;

[0039] In this embodiment, the number of opened smoke exhaust air supply valves and the number of opened fresh air inlet valves affect the host power of the control host running. So, the above step S304 can be realized through steps A1 to A2:

[0040] Step A1, determining the number of oil fume exhausts of the target terminal machine sending the oil fume exhaust power-on signal and the number of fresh air of the target terminal machine sending the fresh air power-on signal based on the power-on signal;

[0041] In actual use, there are often multiple target terminal devices to be powered on. Since each powered-on target terminal device can only send a range hood power-on signal or a fresh air power-on signal to the control host, the control host can determine the number of exhaust and make-up air valves and the number of fresh air inlet valves to be opened among the multiple target terminal devices based on the multiple power-on signals received.

[0042] Step A2: Determine the first host power of the control host according to the number of range hoods and the number of fresh air units.

[0043] Search for the query host power that matches the number of range hoods and the number of fresh air units in the power query table; wherein, the power query table stores the corresponding relationship between the number of range hoods, the number of fresh air units and the host power; determine the query host power as the first host power. This corresponding relationship can be set according to actual needs and is not limited here.

[0044] Step S306: Control the exhaust and make-up air valve or the fresh air inlet valve to open according to the power-on signal, and, at the first host power, adjust the valve of the flow distribution valve corresponding to the target terminal device to the first angle according to the required air intake volume;

[0045] The control host can open the exhaust and make-up air valve or the fresh air inlet valve on the floor where the target terminal device is located for air make-up or air change according to whether the power-on signal is a range hood power-on signal or a fresh air power-on signal; while opening the exhaust and make-up air valve or the fresh air inlet valve, the valve of the flow distribution valve is also adjusted for air exhaust.

[0046] Step S308: Obtain the first static pressure at the connection pipe on the first target floor and the second static pressure at the connection pipe on the second target floor; wherein, the first target floor and the second target floor are different floors, and, the first target floor is the lowest floor where the target terminal device sending the fresh air power-on signal is located, and the second target floor is the lowest floor where the target terminal device sending the range hood power-on signal is located;

[0047] As Figure 1 shown, the static pressure at the connection pipe can be collected by using the wind pressure sensor 105 installed on the collecting hood branch pipe of the terminal device, and the collected static pressure is sent to the control host.

[0048] The lowest floor can be understood as the lowest floor among the multiple powered-on target terminal devices. For example, the floors where the powered-on target terminal devices are located are 2, 3, 4, 5, 7, 9 respectively. Among them, the floors where the target terminal devices sending the fresh air power-on signal are located are 4 and 9, and the remaining floors are the floors where the target terminal devices sending the range hood power-on signal are located. Then, the first target floor is 4 and the second target floor is 2.

[0049] Step S310, if the first static pressure is greater than or equal to the preset first static pressure range and the second static pressure is greater than or equal to the preset second static pressure range, adjust the valve of the flow distribution valve from the first angle to the second angle corresponding to the first main engine power, so that the first static pressure is within the preset first static pressure range and the second static pressure is within the preset second static pressure range;

[0050] If the first static pressure is greater than or equal to the preset first static pressure range and the second static pressure is greater than or equal to the preset second static pressure range, it indicates that the indoor wind pressure is relatively balanced. There is no need to adjust the main engine power of the control host. Just adjust the valve angle of the flow distribution valve, and the first static pressure can be within the preset first static pressure range and the second static pressure can be within the preset second static pressure range.

[0051] Among them, the first static pressure range and the second static pressure range can be set according to actual needs and are not limited here.

[0052] Step S312, if the first static pressure is greater than or equal to the preset first static pressure range and the second static pressure is less than the preset second static pressure range, or the first static pressure is less than the preset first static pressure range, adjust the main engine power of the control host to the second main engine power, and continue to adjust the valve angle of the flow distribution valve at the second main engine power until the first static pressure is within the preset first static pressure range and the second static pressure is within the preset second static pressure range.

[0053] If the first static pressure is greater than or equal to the preset first static pressure range and the second static pressure is less than the preset second static pressure range, or the first static pressure is less than the preset first static pressure range, it indicates that the indoor wind pressure is extremely unbalanced. It is necessary to further adjust the main engine power of the control host to the second main engine power, where the second main engine power is greater than the first main engine power, to increase the main engine power so that the first static pressure is greater than or equal to the preset first static pressure range, and then readjust the valve angle of the flow distribution valve at the second main engine power, so that the first static pressure is within the preset first static pressure range and the second static pressure is within the preset second static pressure range.

[0054] If, after adjusting the valve angle of the flow distribution valve at the second operating power, the first static pressure and / or the second static pressure are still not within the preset static pressure range, further increase the main engine power of the control host, readjust the valve angle of the flow distribution valve at the increased main engine power, and repeat the above process in a loop.

[0055] If the second main engine power or the increased main engine power is the maximum main engine power of the control host and the first static pressure and / or the second static pressure are still not within the preset static pressure range, an alarm will be issued to prompt the maintenance personnel to perform maintenance. This process will be described in detail below and will not be elaborated here.

[0056] An embodiment of the present application provides a method for air volume adjustment, which can automatically open the smoke exhaust and make-up air valve or the fresh air inlet valve in real time according to the required air intake and the power-on signal of the powered-on terminal device, and automatically adjust the opening angle of the flow distribution valve, forming the automatic adjustment of the valve of the flow distribution valve and the smoke exhaust and make-up air valve, or the valve of the flow distribution valve and the fresh air inlet valve, effectively discharging the kitchen fumes, thereby improving the user experience.

[0057] Another method for air volume adjustment is provided in this embodiment, which is implemented on the basis of the above embodiment; as Figure 4 shown in the flowchart of another method for air volume adjustment, the method for air volume adjustment in this embodiment includes the following steps:

[0058] Step S402, obtain the working condition information sent by the target terminal device that is powered on; wherein, the working condition information carries the power-on signal and the required air intake of the target terminal device, the required air intake is calculated based on the gear information sent by the control panel of the target terminal device, and the power-on signal is the smoke exhaust power-on signal or the fresh air power-on signal;

[0059] Step S404, determine the first host power of the control host according to the power-on signal;

[0060] Step S406, control the smoke exhaust and make-up air valve or the fresh air inlet valve to open according to the power-on signal, and find the first angle that matches the required air intake and the first host power from the first angle query table;

[0061] Among them, the first angle query table stores the corresponding relationship between the angle of the valve of the flow distribution valve and the host power and the required air intake;

[0062] The above corresponding relationship can be understood as that different host powers and required air intakes correspond to the angle of a valve, and this corresponding relationship can be set according to actual needs and is not limited herein.

[0063] Step S408, adjust the angle of the valve of the flow distribution valve corresponding to the target terminal device to the first angle;

[0064] Generally, the flow distribution valve includes a communication unit, a driving motor and a valve. Among them, the control host and the driving motor are both communicatively connected to the communication unit, and the driving motor and the valve are drivingly connected; in the process of adjusting the valve angle, mainly control the driving motor to drive the valve to move to achieve the adjustment of the valve angle. Specifically, send the first angle to the communication unit, so that the communication unit generates a driving instruction based on the first angle and sends the driving instruction to the driving motor, so that the driving motor drives the valve corresponding to the target terminal device to move to the first angle.

[0065] In practical applications, the drive motor is valve-drivably connected to the flow distribution valve so as to drive the valve to move after receiving a drive instruction.

[0066] Step S410: Obtain the first static pressure at the connecting pipe of the first target floor and the second static pressure at the connecting pipe of the second target floor.

[0067] Step S412: If the first static pressure is greater than or equal to the preset first static pressure range and the second static pressure is greater than or equal to the preset second static pressure range, obtain the third static pressure at the connecting pipe of the floor where the target terminal is located under the first main engine power.

[0068] Step S414: Search the second angle query table for a second angle that matches the required air intake volume, the third static pressure, and the first angle.

[0069] Wherein, the second angle query table stores the corresponding relationship between the angle of the valve of the flow distribution valve and the required air intake volume, the third static pressure, and the first angle; the above corresponding relationship can be understood as different static pressures, the first angle, and the required air intake volume corresponding to the angle of a valve, and this corresponding relationship can be set according to actual needs and is not limited herein.

[0070] Step S416: Adjust the valve of the flow distribution valve corresponding to the target terminal from the first angle to the second angle.

[0071] Steps S412 to S416 are such that it is only necessary to adjust the angle of the valve of the flow distribution valve without adjusting the main engine power of the control host to make both the first static pressure and the second static pressure within the corresponding preset static pressure ranges to achieve the best smoke exhaust effect.

[0072] Step S418: If the first static pressure is greater than or equal to the preset first static pressure range and the second static pressure is less than the preset second static pressure range, or the first static pressure is less than the preset first static pressure range, adjust the main engine power of the control host to the second main engine power, and continue to adjust the angle of the valve of the flow distribution valve under the second main engine power until the first static pressure is within the preset first static pressure range and the second static pressure is within the preset second static pressure range.

[0073] The process of readjusting the valve of the flow distribution valve under the second main engine power is the same as that of steps S412 to S416 and will not be elaborated herein.

[0074] Generally, the control host is also communicatively connected to an alarm device, which can be a voice alarm, an audible and visual alarm, an alarm platform, etc., and is not limited herein. In actual use, if the host power of the control host is turned to the preset maximum power, and the first static pressure is not within the preset first static pressure range and / or the second static pressure is not within the preset second static pressure range, an alarm trigger signal is generated; the alarm trigger signal is sent to the alarm device to trigger the alarm device to give an alarm prompt.

[0075] The air volume regulation method provided by the embodiments of the present application can realize the automatic regulation of the valve of the flow distribution valve and the smoke exhaust and makeup air valve, or the valve of the flow distribution valve and the fresh air inlet valve, realize the dynamic distribution of suction, and make the smoking effect and the power distribution of all terminal machines in the flue reach the optimal. Moreover, it can give an alarm prompt in time through the alarm device to avoid the occurrence of a fire.

[0076] Corresponding to the above method embodiment, an embodiment of the present invention provides an air volume regulation device, wherein the device is applied to the control host of a central smoke machine system. The central smoke machine system further includes terminal machines, smoke exhaust and makeup air valves, and fresh air inlet valves on each floor that are communicatively connected to the control host. Each terminal machine is connected to a common flue through a connecting pipe, and a flow distribution valve is arranged on the connecting pipe. The flow distribution valve is communicatively connected to the control host; Figure 5 The structure diagram of an air volume regulation device is shown as Figure 5 shown, and the device includes:
