However, the kitchen space is generally small. When the range hood is running continuously, the entire kitchen space will be drawn into a negative pressure state by the range hood. At this time, if there is no new air supply source, the exhaust effect of the range hood will be greatly reduced, and even the fumes will hardly be exhausted.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0033] Taking into account that the existing window-opening for air supply may cause disturbances in the air flow in the kitchen and cause the escape of oil smoke, and that the kitchen air supply based on the indoor and outdoor pressure difference has problems such as unclear and insufficient air supply volume and delayed air supply, based on this, an air volume adjustment method, device and electronic equipment provided in an embodiment of the present invention can adjust the fan operating power of the air supply fan in real time, so that the adjusted air supply volume is within the air supply volume range determined based on the exhaust air volume. In this embodiment, the air supply volume is accurately determined based on the exhaust air volume, and the air supply and exhaust are closely linked to achieve linked air supply, which effectively discharges kitchen oil smoke, thereby improving the user experience.

[0034] To facilitate understanding of this embodiment, the air volume adjustment method provided by the embodiment of the present invention is first described in detail below. The execution subject is the air supply controller, Figure 1A schematic diagram of the structure of a central range hood system is shown. Figure 1 As shown, the system includes an air supply controller 101 of each floor supply fan 100, and also includes an exhaust air pressure taking pipe 102, an air supply pressure taking pipe 103 and a main control module 105 of a terminal 104 on the same floor as the air supply controller 101 and connected to the exhaust air supply controller 101. One side of the exhaust air pressure taking pipe 102 is installed on the exhaust air duct of the terminal 104 ( Figure 1 The other side is connected to the air supply controller 101, and one side of the air supply pressure pipe 103 is installed in the air supply duct of the air supply fan 100 ( Figure 1 (not shown in the figure), and the other side is connected to the air supply controller 101.

[0035] The exhaust air pressure taking pipe 102 and the supply air pressure taking pipe 103 are pipeline equipment capable of measuring pipeline pressure. In this embodiment, each floor is only equipped with one terminal and supply air fan, so it is sufficient to install one exhaust air pressure taking pipe and one supply air pressure taking pipe on each floor, and the supply air fan can be installed at any position of the kitchen space where the terminal is located as required, which is not limited here.

[0036] This embodiment provides a method for adjusting the air volume. Figure 2 A flow chart of a method for adjusting air volume is shown, and the method specifically comprises the following steps:

[0037] Step S202, receiving a gear position signal sent by a target main control module of a powered-on target terminal to operate a target air supply fan;

[0038] In specific applications, a control panel is provided on each terminal, and the control panel may be a touch panel, a mechanical button panel, an infrared control panel or a mobile terminal panel, etc., and a gear button for controlling the air intake volume is provided on the control panel. The turned-on target terminal can obtain the corresponding gear signal by the user controlling the gear button. When the target terminal is turned on for exhaust operation, the target air supply fan also starts to operate for air supply. The target air supply fan and the target terminal are in the same kitchen space.

[0039] Step S203, obtaining the first pipe internal wind pressure of the exhaust duct of the target terminal collected by the exhaust pressure pipe, and the second pipe internal wind pressure of the supply air duct of the target supply air fan collected by the supply air pressure pipe;

[0040] The first in-duct wind pressure mentioned above includes the in-duct total pressure Pta and the in-duct static pressure Psa of the exhaust duct. Similarly, the second in-duct wind pressure includes the in-duct total pressure Ptb and the in-duct static pressure Psb of the supply air duct.

[0041] Step S206, calculating the exhaust air volume of the exhaust duct based on the wind pressure in the first duct, and calculating the supply air volume of the supply air duct based on the wind pressure in the second duct;

[0042] The difference between the total pressure Pta and the static pressure Psa in the first pipe is used to calculate the difference between them, and the difference result Pa is obtained. The difference between the total pressure Ptb and the static pressure Psb in the second pipe is used to calculate the difference between them, and the difference result Pb is obtained. The Pa value is related to the air volume Q1 (m 3 / h) is linearly related to the square of the coefficient, which is recorded as Ka, and the formula is Pa = KaQ1 2 ; Pb value and air volume Q2 (m 3 / h) is linearly related to the square of the coefficient, which is recorded as Kb and expressed as Pb = KbQ2 2 The values ​​of Ka and Kb are generally constants, which are usually pre-stored in the above-mentioned air supply controller and directly called. Here, the inner diameters of the exhaust duct and the air supply duct are designed to be the same, so Ka≈Kb is taken. According to the above formula, the air volume over a period of time is calculated, and the average is taken after filtering out the bad data to obtain the exhaust air volume Qa of the exhaust duct and the supply air volume Qb of the supply air duct.

[0043] Step S208, determining the range of the supply air volume according to the exhaust air volume;

[0044] In this embodiment, in order to ensure effective exhaust volume while maintaining a slight negative pressure in the kitchen space, the make-up air volume Qb is always controlled within a certain air volume range. Therefore, after the exhaust air volume Qa is calculated and determined through step S208, a determined make-up air volume range (0.85Qa~0.95Qa) can be obtained. The above-mentioned make-up air volume range can be set according to actual needs and is not limited here.

[0045] Step S210: If the monitored make-up air volume is not within the make-up air volume interval, adjust the fan operating power of the target make-up air fan until the make-up air volume is within the make-up air volume interval.

[0046] If Qb<0.85Qa, it is determined that the make-up air volume is insufficient, and the fan operating power of the make-up air fan needs to be increased until the make-up air volume Qb is in the range of 0.85Qa~0.95Qa; if Qb>0.95Qa, it is determined that the make-up air volume is too large, and the fan operating power of the make-up air fan needs to be reduced until the make-up air volume Qb is in the range of 0.85Qa~0.95Qa.

[0047] The specific adjustment process can be achieved through steps A1 to A2:

[0048] Step A1, querying the first fan operating power corresponding to the makeup air volume from the fan operating power query table;

[0049] The fan operating power query table stores the correspondence between the makeup air volume and the fan operating power; the correspondence can be set according to actual needs and is not limited here. The fan operating power query table can be used to find the operating power corresponding to the makeup air volume calculated above, and the found operating power is determined as the first fan operating power of the makeup air fan.

[0050] Step A2, starting from the first fan operating power, successively adjusting the fan operating power of the target supplementary air fan according to a preset power adjustment step length until the supplementary air volume is within the supplementary air volume range.

[0051] Usually, there are multiple specific fan operating powers for the make-up air fan, and different specific fan operating powers correspond to different make-up air volumes. The make-up air volume is adjusted by adjusting the fan operating power of the make-up air fan. In this embodiment, a specified power matching the first fan operating power is found from multiple specific fan operating powers, and the fan operating power of the make-up air fan is increased or decreased from the specified power according to a preset power adjustment step until the make-up air volume is within the make-up air volume range. For example, multiple specific fan operating powers are 20W, 50W, 80W, 120W, 150W, 200W, and 220W. Currently, Qb is less than 0.85Qa, and the fan operating power needs to be increased. If the first fan operating power is 50W, the power adjustment step is 1, and the adjusted second fan operating power is 80W. If the make-up air volume corresponding to the current fan operating power is within the make-up air volume range, there is no need to adjust the fan operating power. If the make-up air volume Qb is still less than 0.85Qa, it is necessary to increase the fan operating power. Similarly, the process of adjusting the fan operating power when the supplementary air volume Qb>0.95Qa is the same as above, which will not be described in detail here. The above power adjustment step can be set according to actual needs and is not limited here.

[0052] The embodiment of the present application provides a method for adjusting air volume, wherein the target air supply fan is operated when a gear position signal sent by a target main control module of a powered-on target terminal is received; the wind pressure in the first pipe of the exhaust duct of the target terminal collected by the exhaust pressure taking pipe and the wind pressure in the second pipe of the supply duct of the target air supply fan collected by the supply pressure taking pipe are obtained; the exhaust air volume of the exhaust duct is calculated based on the wind pressure in the first pipe, and the supply air volume of the supply air duct is calculated based on the wind pressure in the second pipe; the supply air volume interval range is determined according to the exhaust air volume; if the monitored supply air volume is not within the supply air volume interval range, the fan operating power of the target supply air fan is adjusted until the supply air volume is within the supply air volume interval range. The present application can adjust the fan operating power of the supply air fan in real time, so that the adjusted supply air volume is within the supply air volume interval range determined based on the exhaust air volume. In the present embodiment, the supply air volume is accurately determined based on the exhaust air volume. The supply air and the exhaust air are closely linked to realize linkage supply air, which effectively discharges kitchen fumes, thereby improving the user experience.

In this embodiment, the above preset exhaust air volume range is set to 600±50m 3 / h, if the exhaust air volume Qa<550m 3 / h, the exhaust air volume is judged to be insufficient, and it is necessary to increase the main engine operating power and / or increase the opening angle of the power distribution valve to increase the exhaust air volume until the exhaust air volume Qa is 600±50m 3 / h range; if the exhaust air volume Qa>650m 3 / h, the exhaust air volume is judged to be too large, and it is necessary to reduce the main engine operating power and / or reduce the opening angle of the power distribution valve to reduce the exhaust air volume until the exhaust air volume Qa is 600±50m 3 / h range.

[0063] In this embodiment, the exhaust air volume can be adjusted through steps B1 to B2:

[0064] Step B1, if the monitored exhaust air volume is less than the preset exhaust air volume interval and the first valve angle is not the maximum valve angle, or the monitored exhaust air volume is greater than the preset exhaust air volume interval and the first valve angle is not the minimum valve angle, the angle of the valve of the power distribution valve is adjusted successively according to the preset valve angle adjustment step until the exhaust air volume is within the preset exhaust air volume interval or the angle of the valve of the power distribution valve reaches the maximum valve angle;

[0065] Among them, the first valve angle and the first host operating power are determined according to the operating condition information carried in the gear signal when the target terminal starts to run. After the host receives the gear signal, the operating condition information carried in the gear signal is extracted; the host is adjusted to the first host operating power according to the air intake volume required by the target terminal; under the first host operating power, the valve angle of the power distribution valve corresponding to the target terminal is adjusted to the first valve angle according to the operating condition information.

[0066] Among them, the working condition information carries the air intake volume required by the target terminal and the floor information where it is located, and 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 is calculated based on the gear information. The target main control module is pre-configured with the floor information where the target terminal is located; in this embodiment, the main control module of each terminal is pre-configured with the floor information of the floor where the terminal is located, and the floor information can be understood as the unique identification information of the floor, which can be represented by the floor number, and the representation method of the floor information is not limited here. The air intake volume corresponding to the gear signal can be further queried in the air intake query table, wherein the corresponding relationship between the gear signal and the air intake volume is stored in the air intake query table.

[0067] The host pre-stores a host operating power query table in the host operating power query table, which stores the correspondence between the host operating power and the air intake volume. The correspondence can be set according to actual needs and is not limited here. The host operating power corresponding to the air intake volume required by the target terminal can be found through the host operating power query table, and the found host operating power is determined as the first host operating power.

[0068] Determining the first valve angle of the power distribution valve based on the operating power and operating condition information of the first host is also achieved by looking up a table. Specifically, the first valve angle that matches the operating power and operating condition information of the first host is searched in the angle adjustment data table; wherein the angle adjustment data table stores the correspondence between the valve angle of the power distribution valve and the operating power and operating condition information; and adjusting the valve angle of the power distribution valve corresponding to the target terminal to the first valve angle.

[0069] The above correspondence can be understood as different host operating power and working condition information corresponding to the angle of a valve. The correspondence can be set according to actual needs and is not limited here.

[0070] In this embodiment, when the exhaust air volume is less than the preset exhaust air volume interval and the first valve angle is not the maximum valve angle, or the exhaust air volume is greater than the preset exhaust air volume interval and the first valve angle is not the minimum valve angle, the exhaust air volume can be adjusted by adjusting the angle of the valve of the power distribution valve. The specific process of adjusting the valve is: searching for a first specified angle matching the first valve angle in the angle adjustment data table; wherein the angle adjustment data table also stores a plurality of specified angles corresponding to the valves that increase in stages; starting from the specified angle, the angle of the valve of the power distribution valve is adjusted successively according to the valve angle adjustment step.

[0071] For example, the angle adjustment data table stores step-by-step increasing designated angles of 3 degrees, 8 degrees, 10 degrees, 15 degrees, 40 degrees, 70 degrees, 90 degrees, and 100 degrees. If the first designated angle matched by the first angle is 15 degrees, and the exhaust air volume is less than the preset exhaust air volume range, the valve angle needs to be increased. If the valve angle adjustment step is 2, the angle of the valve after the first adjustment is 70 degrees. If the exhaust air volume corresponding to the current valve angle is within the preset exhaust air volume range, there is no need to adjust the valve angle. If the exhaust air volume is still less than the preset exhaust air volume range, the valve angle needs to be increased. Similarly, the process of adjusting the valve angle when the exhaust air volume is greater than the preset exhaust air volume range is the same as above and will not be repeated here. The above valve angle adjustment step can be set according to actual needs and is not limited here.

[0072] Step B2, if the monitored exhaust air volume is less than the preset exhaust air volume interval and the first valve angle is the maximum valve angle, or the monitored exhaust air volume is greater than the preset exhaust air volume interval and the first valve angle is the minimum valve angle, adjust the operating power of the host to the second host operating power, and continue to adjust the valve angle of the power distribution valve under the second host operating power until the exhaust air volume is within the preset exhaust air volume interval; wherein the second host operating power is greater than or less than the first host operating power.

[0073] When the valve angle cannot be adjusted or the exhaust air volume is still not within the preset exhaust air volume range after the valve is adjusted to the maximum valve angle or the minimum valve angle, the exhaust air volume can be adjusted by adjusting the host operating power of the host.

[0074] Under the second operating power, the angle of the valve of the power distribution valve is readjusted until the exhaust air volume is within the preset exhaust air volume range or the angle of the valve of the power distribution valve reaches the maximum valve angle or the minimum valve angle. The process of adjusting the angle of the valve of the power distribution valve is the same as above and will not be repeated here.

[0075] If the exhaust air volume is still not within the preset exhaust air volume range after the valve angle of the power distribution valve is adjusted under the second operating power, the host operating power of the main engine is increased or decreased, and the valve angle of the power distribution valve is readjusted under the increased or decreased host operating power, and the above process is repeated.

[0076] If the second operating power or the increased operating power is the maximum host operating power, if the exhaust air volume is still not within the preset exhaust air volume range, an alarm may be issued to prompt maintenance personnel or users to perform maintenance.

[0077] Step S510, determining the range of the supply air volume according to the exhaust air volume;

[0078] Step S512: If the monitored make-up air volume is not within the make-up air volume interval, adjust the fan operating power of the target make-up air fan until the make-up air volume is within the make-up air volume interval.

[0079] Since the above-mentioned exhaust air volume is adjusted in real time, the determined make-up air volume range will also change accordingly, causing the make-up air volume to be adjusted in real time to meet the make-up air requirements. Since the exhaust and make-up air are carried out in conjunction, the kitchen can be effectively exhausted and made-up, and the fumes can be discharged in time.

[0080] Usually, in order to eliminate the remaining oil smoke in the kitchen as much as possible after the target terminal is shut down, the main unit, the power distribution valve and the air supply fan can be shut down for a period of time after the target terminal is shut down. Specifically, a stop signal sent by the target main control module of the target terminal is received; the host is triggered to receive the stop signal within a preset time, so that the host generates a first stop control instruction corresponding to the stop signal to control the host and the power distribution valve to close, and generates a second stop control instruction corresponding to the stop signal within a preset time to control the fan to stop running.

[0081] Usually, a switch button is also provided on the control panel. After receiving the switch button signal of the switch button, the control panel sends a stop signal corresponding to the switch button signal to the main control module. The main control module sends the stop signal to the air supply controller. The air supply controller can stop the operation of the fan within a preset time. At the same time, after the host receives the stop signal within the preset time, the host and the power distribution valve are closed. The above preset time can be set according to actual needs and is not limited here.
