Detailed implementation manners

[0032] To make the objectives, 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. Apparently, 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 protection scope of the present invention.

[0033] Currently, the damper of the terminal can only be controlled by the user triggering the gear button on the control panel, and cannot achieve adaptive control, thus reducing the user experience. Based on this, a method, device, and central range hood system for air volume regulation provided by the embodiments of the present invention can automatically adjust the opening and closing angles of the power distribution valve and the terminal damper in real time according to the working condition information of the air intake volume of the powered - on terminal and the floor information where it is located, forming a linkage adjustment between the terminal damper and the power distribution valve, achieving the effect of dual - drive and dual - adjustment, enabling the range hood to have a better smoke - gathering effect. At the same time, it liberates the user's hands for adjusting the damper, effectively improving the user experience.

[0034] For the convenience of understanding this embodiment, the method for adjusting the air volume provided by the embodiment of the present invention will be introduced in detail below. The execution subject is the central range hood host of the central range hood system. Figure 1 shows a schematic structural diagram of a central range hood system, as Figure 1 shown. The central range hood system includes a central range hood host 100 and a main control module 102 of each floor terminal 101 communicatively connected to the central range hood host 100. Each terminal 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 power distribution valve 103 is provided on the connecting pipe, and the power distribution valve 103 is communicatively connected to the central range hood host 100. Figure 1 Only 3 terminals 101 are shown in the figure. Therefore, there are 3 main control modules 102 and 3 power distribution valves 103. In actual use, the number of terminals 101 connected to the central range hood host 100 can be set according to actual needs and will not be limited here.

[0035] In this embodiment, only one terminal is configured on each floor. Therefore, only one power distribution valve needs to be installed on the connecting pipe of each floor. For the convenience of understanding, Figure 2 shows another schematic structural diagram of a central range hood system. Figure 2 Taking the 5 floors shown in the figure as an example, one terminal 101 is installed on each floor. The 5 terminals are respectively connected to the common flue 201 through connecting pipes 200. Moreover, the power distribution valve 103 provided on each connecting pipe and each terminal 101 are communicatively connected to the central range hood host 100.

[0036] Based on the above central range hood host, the embodiment of the present invention provides a method for adjusting the air volume. Figure 3 shows a flowchart of a method for adjusting the air volume, as Figure 3 shown. The method includes the following steps:

[0037] Step S302, obtaining the working condition information sent by the target main control module of the target terminal that is powered on;

[0038] Among them, the working condition information carries the required air intake volume of the target terminal and the floor information where it is located. The air intake volume is obtained by the target main control module by obtaining the gear information sent by the control panel of the target terminal and calculating based on the gear information. The floor information where the target terminal is located is pre-configured in the target main control module.

[0039] In specific applications, a control panel is provided on each terminal. The above control panel can be a touch panel, a mechanical button panel, an infrared control panel, a mobile terminal panel, etc. And a gear button for controlling the air intake volume is set on the control panel. The target terminal that is powered on can obtain the corresponding gear information by the user controlling the gear button, and further, the air intake volume corresponding to the gear information can be queried in the air intake query table, where the corresponding relationship between the gear information and the air intake volume is stored in the air intake query table.

[0040] In this embodiment, the floor information of the floor where each terminal is located is pre-configured in the main control module of each terminal. This floor information can be understood as the unique identification information of the floor and can be represented by the floor number. The representation method of the floor information is not limited here.

[0041] Step S304, adjust the central range hood main unit to the first operating power according to the air intake volume required by the target terminal.

[0042] In this embodiment, the above central range hood main unit stores a power query table, and the corresponding relationship between the operating power and the air intake volume is stored in the power query table. This corresponding relationship can be set according to actual needs and is not limited here. Through the power query table, the operating power corresponding to the air intake volume required by the target terminal can be found, and the found operating power is determined as the first operating power.

[0043] Step S306, at the first operating power, adjust the angle of the valve of the power distribution valve corresponding to the target terminal according to the working condition information.

[0044] Step S308, if the angle of the valve of the power distribution valve is adjusted to the first extreme angle corresponding to the first operating power, and the current smoke concentration on the floor where the target terminal is located is not within the preset concentration range, at the first operating power, adjust the angle of the air damper of the target terminal according to the working condition information.

[0045] The above first extreme angle refers to the maximum angle at which the central range hood main unit can adjust the valve at the first operating power, rather than the maximum angle at which the valve of the actual power distribution valve can open and close.

[0046] After the angle of the valve of the power distribution valve is adjusted to the extreme angle, the current smoke concentration on the floor where the target terminal is located is not within the preset concentration range, indicating that the exhaust air volume still needs to be increased to discharge the smoke. Therefore, when the angle of the valve of the power distribution valve cannot be adjusted any further, the angle of the air damper of the target terminal is adjusted to achieve the purpose of increasing the exhaust air volume.

[0047] The measurement of the current smoke concentration above is collected by a smoke sensor module installed on the periphery of the terminal housing. The smoke sensor module is communicatively connected to the main control module of the terminal to send the collected current smoke concentration to the main control module. Then, the central range hood main unit obtains the current smoke concentration from the main control module. Moreover, the above preset concentration range can be set according to actual needs and will not be limited here.

[0048] Step S310, if the angle of the air damper of the target terminal is adjusted to the second extreme angle corresponding to the first operating power, and the current smoke concentration on the floor where the target terminal is located is not within the preset concentration range, adjust the operating power of the central range hood main unit to the second operating power, and continue to adjust the angle of the valve of the power distribution valve and / or the angle of the air damper of the target terminal at the second operating power until the current smoke concentration on the floor where the target terminal is located is within the preset concentration range.

[0049] The above second extreme angle refers to the maximum angle at which the central range hood main unit can adjust the air damper at the first operating power, rather than the maximum angle at which the actual air damper can open and close.

[0050] After the angles of the valve of the power distribution valve and the air damper are both adjusted to the extreme angles at the first operating power, and the current smoke concentration on the floor where the target terminal is located is not within the preset concentration range, it indicates that the exhaust air volume still needs to be increased to discharge the smoke. Therefore, when the angles of the valve of the power distribution valve and the air damper cannot be adjusted further, adjust the operating power of the central range hood main unit to the second operating power.

[0051] Among them, the second operating power is greater than the first operating power. At the second operating power, readjust the angle of the valve of the power distribution valve and / or the angle of the air damper of the target terminal until the current smoke concentration on the floor where the target terminal is located is within the preset concentration range. The process of adjusting the angle of the valve of the power distribution valve and / or the angle of the air damper of the target terminal is the same as the above steps S306 - S308 and will not be elaborated here.

[0052] If, at the second operating power, after the angles of the valve of the power distribution valve and the air damper are adjusted to the limit angles, the current smoke concentration is still not within the preset concentration range, then increase the operating power of the central range hood main unit again, and readjust the angle of the valve of the power distribution valve and / or the angle of the air damper of the target terminal at the increased operating power. The angle adjustment process is the same as steps S306 - S308 and will not be elaborated here.

[0053] If the second operating power or the increased operating power is the maximum operating power of the main unit of the central range hood, and if the current smoke concentration is still not within the preset concentration range, an alarm is issued to prompt the maintenance personnel to perform maintenance. This process will be described in detail below and will not be elaborated here.

[0054] In this embodiment, the adjustment of the operating power is achieved through a power query table. Among them, the power query table stores multiple specific host powers that increase step by step. Taking the adjustment from the first operating power to the second operating power as an example, the specified power that matches the first operating power is found from the multiple specific host power information, and the operating power of the host is increased from the specified power to the second operating power according to the preset power adjustment step size; among them, the power adjustment step size can be set according to actual needs and will not be limited here. For example, the specific host powers stored in the power query table that increase step by step are 100W, 200W, 300W, 400W, 600W, 800W, 1000W. If the first operating power is 200W and the power adjustment step size is 3, the adjusted second operating power is 600W.

[0055] The embodiment of the present application provides a method for air volume adjustment, which automatically adjusts the opening and closing angles of the power distribution valve and the terminal machine air damper in real time according to the working conditions information of the air intake volume and the floor information of the powered-on terminal machine obtained, forming a linkage adjustment between the terminal machine air damper and the power distribution valve, achieving the effect of double drive and double adjustment, enabling the range hood to have a better smoke collection effect. At the same time, it liberates the user's hands for adjusting the air damper and effectively improves the user experience.

[0056] This embodiment provides another method for air volume adjustment, which is implemented on the basis of the above embodiment; this embodiment focuses on describing the specific implementation methods of adjusting the valve angle and the air damper angle. 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:

[0057] Step S402, obtain the working conditions information sent by the target main control module of the powered-on target terminal machine;

[0058] Among them, the working conditions information carries the air intake volume required by the target terminal machine and the floor information where it is located, and the air intake volume is obtained by the target main control module by acquiring the gear information sent by the control panel of the target terminal machine and calculating based on the gear information. The floor information where the target terminal machine is located is pre-configured in the target main control module;

[0059] Step S404, adjust the main unit of the central range hood to the first operating power according to the air intake volume required by the target terminal machine;

[0060] Step S406, at the first operating power, adjust the valve of the power distribution valve corresponding to the target terminal to the first angle according to the working condition information, and monitor the current smoke concentration on the floor where the target terminal is located;

[0061] The adjustment angle of the valve can be found by querying the preset first angle adjustment data table to find out the specific adjustment angle corresponding to the first operating power and the working condition information, and then adjust the valve according to the found adjustment angle.

[0062] The specific valve adjustment process can be realized by steps A1 to A2:

[0063] Step A1, find the first angle that matches the first operating power and the working condition information in the first angle adjustment data table; among them, the first angle adjustment data table stores the corresponding relationship between the angle of the valve of the power distribution valve and the operating power and the working condition information;

[0064] The above corresponding relationship can be understood as different operating powers and working condition information corresponding to the angle of a valve, and this corresponding relationship can be set according to actual needs and is not limited here.

[0065] Step A2, adjust the angle of the valve of the power distribution valve corresponding to the target terminal to the first angle.

[0066] Generally, the power distribution valve includes a communication module, a driving motor and a valve. Among them, the central range hood main unit and the driving motor are both communicatively connected to the communication module, 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 module, so that the communication module 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 to move to the first angle.

[0067] In actual application, the driving motor is drivingly connected to the valve of the power distribution valve to facilitate driving the valve to move after receiving the driving instruction.

[0068] Step S408, if the current smoke concentration is not within the concentration range, adjust the angle of the valve of the power distribution valve step by step according to the preset valve angle adjustment step size until the current smoke concentration is within the concentration range or the angle of the valve of the power distribution valve reaches the first extreme angle corresponding to the first operating power;

[0069] The specific process of gradually adjusting the angle of the valve of the power distribution valve is as follows: Search for the first specified angle that matches the first angle in the first angle adjustment data table; wherein, the first angle adjustment data table also stores multiple specified angles that increase progressively corresponding to the valve; Starting from the first specified angle, gradually adjust the angle of the valve of the power distribution valve according to the valve angle adjustment step size.

[0070] For example, the specified angles stored in the first angle adjustment data table that increase progressively are 5 degrees, 10 degrees, 15 degrees, 20 degrees, 60 degrees, 80 degrees, 100 degrees, and 120 degrees. If the first specified angle that matches the first angle is 20 degrees and the valve angle adjustment step size is 2, the angle of the valve after the first adjustment is 80 degrees, and the angle of the valve after another adjustment is 120 degrees. Among them, the valve angle adjustment step size can be set according to actual needs and is not limited here.

[0071] Step S410, if the angle of the valve of the power distribution valve is adjusted to the first extreme value angle corresponding to the first operating power, and the current smoke concentration on the floor where the target terminal is located is not within the preset concentration range, at the first operating power, adjust the air door corresponding to the target terminal to the second angle according to the working condition information, and monitor the current smoke concentration on the floor where the target terminal is located;

[0072] The adjusted angle of the air door can be found by querying the preset second angle adjustment data table to find out the specific adjusted angle corresponding to the first operating power and the working condition information, and then adjust the air door according to the found adjusted angle.

[0073] The specific air door adjustment process can be implemented by steps B1 to B2:

[0074] Step B1, search for the second angle that matches the first operating power and the working condition information in the second angle adjustment data table; wherein, the second angle adjustment data table stores the corresponding relationship between the angle of the air door and the operating power and the working condition information;

[0075] Specifically, the above corresponding relationship can be understood as different operating powers and working condition information corresponding to an angle of the air door, and this corresponding relationship can be set according to actual needs and is not limited here.

[0076] Step B2, adjust the angle of the air door corresponding to the target terminal to the second angle.

[0077] Generally, the air door includes a push rod motor and an air door baffle, and the main control module is communicatively connected to the push rod motor; for the sake of easy understanding, Figure 5 shows a schematic installation diagram of a terminal structure, such as Figure 5As shown in the figure, taking the example that the smoke collecting chamber is divided into a left smoke collecting chamber 500 and a right smoke collecting chamber 501, a damper is installed at each smoke collecting chamber. Among them, the push rod motor 502 and the damper baffle 503 are installed on the left smoke collecting chamber 500 side, and a push connection is provided between the push rod motor 502 and the damper baffle 503. The push rod motor 504 and the damper baffle 505 are installed on the right smoke collecting chamber 501 side, and a push connection is provided between the push rod motor 504 and the damper baffle 505. Moreover, the smoke sensor module 506 is respectively installed on the periphery of the terminal housing to collect the current smoke concentration.

[0078] When adjusting the angles of the dampers of the target terminal, it is necessary to adjust the left and right damper baffles simultaneously. The specific process of adjusting the damper angle is as follows: Send the second angle to the main control module of the target terminal, so that the main control module of the target terminal generates a push instruction based on the second angle, and sends the push instruction to the corresponding push rod motors (push rod motor 502 and push rod motor 504) of the target terminal, so that the push rod motor pushes the damper baffles (damper baffle 503 and damper baffle 505) of the target terminal to move to the second angle.

[0079] During actual use, the longer the push rod of the push rod motor extends, the larger the opening angle of the damper baffle, the larger the air inlet area of the smoke collecting chamber, and the smoother the smoke inlet. Generally, there are two ways to open the damper baffle. One is to open it outward from the outside of the smoke collecting chamber, and the other is to open it inward from the smoke collecting chamber, corresponding to Figure 6 Figure a and Figure b of the schematic diagram of the damper baffle opening method shown in, from Figure 6 it can be seen that the opening and closing angles of the double-chamber damper baffle are θ, θ1, and θ2 respectively. The opening and closing angle θ2 is the largest, and the opening and closing angle θ is the smallest. When the damper is opened at different angles, the air inlet volume of the smoke collecting chamber is different, and the smoking effect is also different.

[0080] The adjustment of the air inlet area size of the double chamber is controlled by the damper angle, and the air inlet area size can also be adjusted by driving the up and down translation distance of the entire damper. The opening and closing positions of the damper baffle are not limited to Figure 6 the smaller angle θ, the larger angle θ1, and the largest angle θ2 shown in. The controlled positions can be appropriately increased and decreased. Moreover, the adjustment of the air volume can also be achieved on the terminal with a single smoke collecting chamber.

[0081] Step S412, if the current smoke concentration is not within the concentration range, adjust the angle of the damper corresponding to the target terminal step by step according to the preset damper angle adjustment step size until the current smoke concentration is within the concentration range or the angle of the damper corresponding to the target terminal reaches the second extreme angle corresponding to the first operating power;

[0082] The specific process of gradually adjusting the angle of the air damper corresponding to the target terminal is as follows: Search for the second specified angle that matches the second angle in the second angle adjustment data table; wherein, the second angle adjustment data table also stores multiple specified angles that increase progressively corresponding to the air damper; starting from the second specified angle, gradually adjust the angle of the air damper corresponding to the target terminal according to the air damper angle adjustment step size.

[0083] For example, the specified angles stored in the second angle adjustment data table that increase progressively are 3 degrees, 15 degrees, 18 degrees W, 20 degrees, 60 degrees, 80 degrees, 100 degrees, and 120 degrees. If the second specified angle that matches the second angle is 18 degrees and the valve angle adjustment step size is 1, the angle of the air damper after the first adjustment is 20 degrees, and the angle of the air damper after another adjustment is 60 degrees. Among them, the air damper angle adjustment step size can be set according to actual needs and is not limited here.

[0084] Step S414, if the angle of the air damper of the target terminal is adjusted to the second extreme angle corresponding to the first operating power and the current smoke concentration on the floor where the target terminal is located is not within the preset concentration range, adjust the operating power of the central range hood main unit to the second operating power, and continue to adjust the angle of the valve of the power distribution valve and / or the angle of the air damper of the target terminal under the second operating power until the current smoke concentration on the floor where the target terminal is located is within the preset concentration range;

[0085] Step S416, if the operating power of the central range hood main unit is turned up to the preset maximum power and the current smoke concentration on the floor where the target terminal is located is not within the preset concentration range, generate an alarm trigger signal;

[0086] Generally, the central range hood main unit is also communicatively connected to an alarm device, which can be a voice alarm, an audible and visual alarm, or an alarm platform, etc., and is not limited here.

[0087] If the operating power of the central range hood main unit is turned up to the preset maximum power, and at this maximum operating power, when the opening and closing angles of the valve and the air damper also reach the extreme angles at the maximum operating power, and the current smoke concentration on the floor where the target terminal is located is still not within the preset concentration range, then generate an alarm trigger signal to send the alarm trigger signal to the alarm device, and the maintenance personnel repair the central range hood system according to the alarm prompt issued by the alarm device.

[0088] Step S418, send the alarm trigger signal to the alarm device to trigger the alarm device to give an alarm prompt.
