DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] In existing residential buildings, kitchens and bathrooms are both equipped with corresponding public exhaust ducts, and the kitchen exhaust and bathroom exhaust are two independent exhaust systems. However, there is a technical problem of high equipment cost when two exhaust systems are set up. In view of this, an embodiment of the present invention provides a kitchen and bathroom integrated exhaust system to solve the above technical problems.

[0029] Embodiment 1

[0030] Figure 1 A schematic diagram of a kitchen and bathroom integrated exhaust system according to an embodiment of the present invention is shown in FIG. Figure 1 As shown, the integrated kitchen and bathroom exhaust system includes: an exhaust main unit 100, a connecting air duct 200, a kitchen air volume master control valve 300, a bathroom air volume master control valve 400, a plurality of kitchen exhaust terminals 500 and a plurality of bathroom exhaust terminals 600.

[0031] The exhaust main unit 100 is arranged at the top of the building, and is respectively connected to the kitchen air volume master control valve 300 and the bathroom air volume master control valve 400 through the connecting air duct 200 arranged at the top of the building; the kitchen air volume master control valve 300 is arranged at the confluence section of the kitchen public exhaust duct, and the bathroom air volume master control valve 400 is arranged at the confluence section of the bathroom public exhaust duct.

[0032] The kitchen air volume master control valve 300 is used to adjust the exhaust flow rate of the kitchen public exhaust duct.

[0033] The bathroom air volume master control valve 400 is used to adjust the exhaust flow rate of the bathroom public exhaust duct.

[0034] The exhaust main unit 100 is used to provide power for the integrated kitchen and bathroom exhaust system to assist in extracting and discharging the dirty gas in the kitchen and the dirty gas in the bathroom; wherein the dirty gas in the kitchen refers to the gas discharged from the kitchen exhaust terminal 500 through the kitchen air volume master control valve 300; the dirty gas in the bathroom refers to the gas discharged from the bathroom exhaust terminal 600 through the bathroom air volume master control valve 400.

[0035] The integrated kitchen and bathroom exhaust system provided in the embodiment of the present invention combines the bathroom exhaust system with the kitchen exhaust system, taking into account that the bathroom exhaust volume is relatively small, so that the exhaust main unit 100 arranged on the top of the building can simultaneously provide auxiliary exhaust for the kitchen and the bathroom.

[0036] Specifically, the kitchen and bathroom integrated exhaust system includes an exhaust main unit 100 arranged at the top of the building, a connecting air duct 200 arranged at the top of the building, a kitchen air volume master control valve 300 arranged at the kitchen public exhaust duct confluence section, a bathroom air volume master control valve 400 arranged at the bathroom public exhaust duct confluence section, a plurality of kitchen exhaust terminals 500 and a plurality of bathroom exhaust terminals 600, the kitchen exhaust terminal 500 is installed in each user's kitchen, and the bathroom exhaust terminal 600 is installed in each user's bathroom. The embodiment of the present invention does not specifically limit the number of kitchen exhaust terminals 500 and the number of bathroom exhaust terminals 600. Generally, each user on each floor of a residential building is equipped with a kitchen exhaust terminal 500 and a bathroom exhaust terminal 600.

[0037] It can be seen from the above description that the kitchen air volume master control valve 300 is set at the confluence section of the kitchen public exhaust duct, and the bathroom air volume master control valve 400 is set at the confluence section of the bathroom public exhaust duct. That is, the embodiment of the present invention does not limit the specific installation positions of the kitchen air volume master control valve 300 and the bathroom air volume master control valve 400. As long as each master control valve is installed in the corresponding exhaust duct confluence section and ensures that the kitchen air volume master control valve 300 can adjust the exhaust flow rate of the kitchen public exhaust duct, the bathroom air volume master control valve 400 can adjust the exhaust flow rate of the bathroom public exhaust duct.

[0038] When the user uses the kitchen exhaust terminal 500 and the bathroom exhaust terminal 600, the exhaust host 100 can uniformly assist in extracting and discharging the kitchen dirty gas and the bathroom dirty gas by connecting the air duct 200.

[0039] In the integrated kitchen and bathroom exhaust system provided by the present invention, the exhaust main unit 100 is respectively connected to the kitchen air volume master control valve 300 and the bathroom air volume master control valve 400 through the connecting air duct 200, so that the dirty gas discharged by the kitchen exhaust terminal 500 through the kitchen air volume master control valve 300 and the dirty gas discharged by the bathroom exhaust terminal 600 through the bathroom air volume master control valve 400 share the same exhaust main unit 100 for auxiliary extraction and discharge, which effectively reduces the cost of the exhaust system of the residential building.

[0040] Generally, the function of the exhaust main unit 100 is limited to auxiliary extraction and exhaust, and has no odor purification function. If the dirty gas in the kitchen and the dirty gas in the bathroom are directly discharged into the atmosphere, it is easy to cause environmental pollution. Therefore, in an optional embodiment, Figure 2As shown, the exhaust main unit 100 includes: a fan 101 and an air purification device 102 .

[0041] The fan 101 is used to provide power for the integrated kitchen and bathroom exhaust system; the air purification device 102 is used to purify the polluted gas transported by the connected air duct 200.

[0042] In the embodiment of the present invention, the exhaust main unit 100 uses the fan 101 therein to provide power for the exhaust system, and can extract dirty gas from the kitchen public exhaust duct and the bathroom public exhaust duct, and before discharging into the atmosphere, the dirty gas is purified by the air purification device 102 provided in the main unit, thereby achieving the effect of reducing air pollution. The embodiment of the present invention does not specifically limit the installation position of the air purification device 102, and it can be installed before the fan 101 or after the fan 101, as long as it ensures that the dirty gas can pass through the air purification device 102.

[0043] In an optional embodiment, if Figure 3 As shown, the kitchen exhaust terminal 500 includes: a kitchen flow power distribution valve 501 and a range hood 502 .

[0044] The kitchen flow power distribution valve 501 is located at the end of the air duct of the range hood 502 and is close to the kitchen public exhaust duct interface; the kitchen flow power distribution valve 501 is interlocked with the range hood 502 to adjust the exhaust volume of the kitchen on the corresponding floor.

[0045] In the embodiment of the present invention, each kitchen exhaust terminal 500 is provided with a kitchen flow power distribution valve 501 and a range hood 502. The kitchen flow power distribution valve 501 is arranged at the end of the air duct of the range hood 502 and is close to the kitchen common exhaust duct interface. Only when the kitchen flow power distribution valve 501 is in the open state, the oil smoke extracted by the range hood 502 can be discharged to the kitchen common exhaust duct. Therefore, the kitchen flow power distribution valve 501 and the range hood 502 connected thereto in the embodiment of the present invention are interlocked. When the range hood 502 is turned on, the kitchen flow power distribution valve 501 can obtain a power-on signal, thereby allowing the kitchen oil smoke to be discharged smoothly; when the range hood 502 is in the off state, the kitchen flow power distribution valve 501 is in the closed state, thereby effectively preventing odor contamination. Therefore, the kitchen flow power distribution valve 501 can adjust the exhaust volume of the kitchen on the corresponding floor.

[0046] Furthermore, in an embodiment of the present invention, the kitchen flow power distribution valve 501 is communicatively connected to the exhaust host 100 (either wired or wirelessly). When the kitchen flow power distribution valve 501 obtains a power-on signal, it sends a power-on command to the exhaust host 100 to turn on the exhaust host 100 and perform auxiliary extraction and exhaust.

[0047] In an optional embodiment, if Figure 4 As shown, the bathroom exhaust terminal 600 includes: a bathroom flow power distribution valve 601 and a ventilator 602.

[0048] The bathroom flow power distribution valve 601 is located at the end of the air duct of the ventilator 602 and is close to the bathroom public exhaust duct interface; the bathroom flow power distribution valve 601 is interlocked with the ventilator 602 to adjust the exhaust volume of the bathroom on the corresponding floor.

[0049] In the embodiment of the present invention, each bathroom exhaust terminal 600 is provided with a bathroom flow power distribution valve 601 and a ventilator 602. The bathroom flow power distribution valve 601 is located at the end of the air duct of the ventilator 602 and is close to the bathroom public exhaust duct interface. Only when the bathroom flow power distribution valve 601 is in the open state, the gas extracted by the ventilator 602 can be discharged to the bathroom public exhaust duct. Therefore, the bathroom flow power distribution valve 601 and the ventilator 602 connected thereto in the embodiment of the present invention are interlocked. When the ventilator 602 is turned on, the bathroom flow power distribution valve 601 can obtain a power-on signal, thereby allowing the gas in the bathroom to be discharged smoothly; when the ventilator 602 is in the off state, the bathroom flow power distribution valve 601 is in the closed state, thereby effectively preventing odor. Therefore, the bathroom flow power distribution valve 601 can adjust the exhaust volume of the bathroom on the corresponding floor.

[0050] Furthermore, in an embodiment of the present invention, the bathroom flow power distribution valve 601 is communicatively connected to the exhaust main unit 100 (either wired or wirelessly). When the bathroom flow power distribution valve 601 obtains a power-on signal, it sends a power-on command to the exhaust main unit 100 to turn on the exhaust main unit 100 and perform auxiliary extraction and exhaust.

[0051] In an optional embodiment, the bathroom exhaust terminal 600 also includes: a first condensation air duct 603 and a second condensation air duct 604; the height of the first condensation air duct 603, the height of the second condensation air duct 604 and the height of the ventilator 602 are all lower than the height of the horizontal section connecting the air duct in the bathroom exhaust terminal 600.

[0052] The first end of the first condensation air duct 603 is connected to the bathroom flow power distribution valve 601, and the second end of the first condensation air duct 603 is connected to the first end of the ventilator 602; the first end of the second condensation air duct 604 is connected to the second end of the ventilator 602, and the second end of the second condensation air duct 604 is connected to the bathroom exhaust port; a drain pipe is provided at the bottom of the ventilator 602 for discharging condensed water in the condensation air duct.

[0053] From the description of the installation positions of the first condensation air duct 603 and the second condensation air duct 604 in the above text, it can be known that the embodiment of the present invention installs the first condensation air duct 603 and the second condensation air duct 604 on both sides of the ventilator 602 respectively, and the heights of the first condensation air duct 603, the second condensation air duct 604 and the ventilator 602 are all lower than the height of the horizontal section connecting the air duct in the bathroom exhaust terminal 600. Therefore, the condensed water generated in the two condensation air ducts can flow into the bottom of the ventilator 602 under the action of gravity. A drain pipe is provided at the bottom of the ventilator 602, which can discharge the condensed water in the condensation air duct in time, thereby reducing the air humidity in the public exhaust duct of the bathroom.

[0054] In an optional implementation, the bathroom exhaust terminal 600 further includes: a humidity sensor 605 .

[0055] The humidity sensor 605 is disposed inside the target condensation air duct and is used to monitor the gas humidity in the target condensation air duct; wherein the target condensation air duct includes any one of the following: a first condensation air duct 603 , a second condensation air duct 604 .

[0056] Furthermore, in the bathroom exhaust terminal 600 provided in the embodiment of the present invention, a humidity sensor 605 is also provided inside the target condensation duct (the first condensation duct 603 or the second condensation duct 604) for detecting the gas humidity in the target condensation duct. The humidity sensor 605 can be connected to the user's mobile terminal for communication, so that the user can judge whether it is necessary to turn on the ventilator 602 for exhaust according to the humidity in the target condensation duct. The humidity sensor 605 can also be connected to the exhaust host 100. The greater the air humidity, the greater the resistance that the exhaust needs to overcome, so that the exhaust host 100 can provide greater exhaust power to ensure timely ventilation of the bathroom.

[0057] In an optional embodiment, the bathroom exhaust terminal 600 further includes: an induction detector 606. The induction detector 606 is in communication connection with the ventilator 602.

[0058] The induction detector 606 is used to monitor the use of the toilet; when the induction detector 606 detects the presence of an active object, the induction detector 606 sends a power-on signal to the ventilator 602 to turn on the ventilator 602.

[0059] Specifically, in order to be able to discharge the gas in the bathroom in time, the bathroom exhaust terminal 600 provided in the embodiment of the present invention also includes a sensing detector 606, and the sensing detector 606 is interlocked with the ventilator 602, that is, when the sensing detector 606 detects an active object in the bathroom, it is determined that the bathroom is in use. At this time, the sensing detector 606 sends a power-on signal to the ventilator 602 to turn on the ventilator 602. Since the ventilator 602 is interlocked with the bathroom flow power distribution valve 601, the bathroom flow power distribution valve 601 is also opened at this time, so that the gas in the bathroom can be discharged smoothly.

[0060] Figure 5 This is a schematic diagram of the structure of an optional kitchen and bathroom integrated exhaust system provided in an embodiment of the present invention. Combined with the content described above, it can be seen that the kitchen and bathroom integrated exhaust system provided in an embodiment of the present invention integrates kitchen exhaust and bathroom exhaust, so that the kitchen public exhaust duct and the bathroom public exhaust duct share the same exhaust main unit 100 for auxiliary extraction and exhaust, thereby effectively reducing the equipment cost of the residential building exhaust system. And each kitchen exhaust terminal 500 and bathroom exhaust terminal 600 are equipped with corresponding flow power distribution valves, which can effectively control the exhaust volume of each terminal accordingly, avoiding problems such as poor exhaust and odor.

[0061] Embodiment 2

[0062] An embodiment of the present invention further provides a kitchen and bathroom integrated exhaust control method, which is mainly applied to the kitchen and bathroom integrated exhaust system provided in the above-mentioned embodiment 1. The kitchen and bathroom integrated exhaust control method provided in the embodiment of the present invention is specifically introduced below.

[0063] Figure 6 is a flow chart of a kitchen and bathroom integrated exhaust control method provided by an embodiment of the present invention, such as Figure 6 As shown, the method mainly includes the following steps:

[0064] Step S102, obtaining the first preset air volume, the second preset air volume and the current working condition of the kitchen and bathroom integrated exhaust system.

[0065] In the prior art, the exhaust method through the public exhaust duct has problems such as poor exhaust and odor contamination in the middle and lower floors during peak usage. In view of this, in the integrated kitchen and bathroom exhaust control method provided by the embodiment of the present invention, while ensuring that the exhaust host provides appropriate wind pressure and air volume, the valve plate opening of the kitchen air volume master control valve, the bathroom air volume master control valve and the flow power distribution valve on each floor is controlled to ensure that the users on the middle and lower floors can also exhaust smoothly, that is, the kitchens of the users on the middle and lower floors can obtain the effective exhaust volume when the smoke exhaust effect is better, and the bathrooms of the users on the middle and lower floors can obtain the effective exhaust volume when the smoke exhaust effect is better.

[0066] The kitchen and bathroom integrated exhaust control method provided in the embodiment of the present invention is mainly applied to the exhaust system provided in the above-mentioned embodiment 1. When controlling the exhaust system, it is necessary to determine the operating power of the exhaust main unit, the opening of the kitchen air volume master control valve, the opening of the bathroom air volume master control valve, the valve plate opening of each kitchen flow power distribution valve and the valve plate opening of each bathroom flow power distribution valve. After determining the above basic information, the kitchen and bathroom integrated exhaust system can operate smoothly based on the above basic information.

[0067] In order to determine the above basic information, the method first needs to obtain the first preset air volume, the second preset air volume and the current working condition of the kitchen and bathroom integrated exhaust system when it is running, wherein the first preset air volume is the air volume required for each range hood to exhaust, and the second preset air volume is the air volume required for each ventilator to exhaust, and the current working condition includes: the number of range hoods turned on, the floors where the range hoods are turned on, the number of ventilators turned on, the floors where the ventilators are turned on, the specifications of the kitchen public exhaust duct, the specifications of the bathroom public exhaust duct and the specifications of the connecting air duct. In the embodiment of the present invention, the first preset air volume can be understood as the effective exhaust volume when the range hood has a better exhaust effect, which is generally a large crotch air volume; the second preset air volume can be understood as the effective exhaust volume when the ventilator has a better exhaust effect, which is generally also a large crotch air volume.

[0068] Step S104, based on the first preset air volume, the second preset air volume and the current operating conditions, determine the static pressure value inside the public exhaust duct on each floor, the total exhaust volume of the exhaust main unit, the operating air pressure of the exhaust main unit, the opening of the kitchen air volume master control valve and the opening of the bathroom air volume master control valve.

[0069] After obtaining the first preset air volume, the second preset air volume and the current working condition of the exhaust system, the static pressure value inside the public exhaust duct of each kitchen floor, the static pressure value inside the public exhaust duct of each bathroom floor, the total exhaust volume of the exhaust host, the operating air pressure of the exhaust host, and the opening of the kitchen air volume master control valve and the opening of the bathroom air volume master control valve can be further determined based on the above information. The specific calculation process of each parameter will be introduced in detail below.

[0070] Step S106, determine the operating frequency of the exhaust host, the valve opening of each kitchen flow power distribution valve and the valve opening of each bathroom flow power distribution valve based on the static pressure value inside the public exhaust duct on each floor, the total exhaust volume of the exhaust host and the operating wind pressure of the exhaust host.

[0071] The total exhaust volume of the exhaust host, the operating air pressure of the exhaust host and the operating frequency of the exhaust host have a certain corresponding relationship. Therefore, the operating frequency of the exhaust host can be determined based on the total exhaust volume and the operating air pressure of the exhaust host, that is, the operating parameters of the exhaust host can be determined.

[0072] The static pressure value inside the public exhaust duct on each floor (kitchen or bathroom) has a certain influence on the valve opening of the corresponding (kitchen or bathroom) flow power distribution valve. Combined with the first preset air volume and the second preset air volume, the valve opening of each kitchen flow power distribution valve and the valve opening of each bathroom flow power distribution valve can be determined.

[0073] In order to minimize the waste of resources, in the embodiment of the present invention, the valve plate opening of the flow power distribution valve of the lowest-level powered-on users is set to the maximum, that is, there is no valve resistance. It should be noted that the lowest level refers to the lowest level among the powered-on floors. Assuming that the floors where the range hoods are powered-on are the 3rd, 5th and 8th floors respectively, the lowest level represents the 3rd floor. The valve plate of the flow power distribution valve on the floors that are not powered-on has no opening, that is, it is in a closed state.

[0074] The kitchen and bathroom integrated exhaust control method provided by the embodiment of the present invention obtains the current operating condition, the first preset air volume and the second preset air volume of the kitchen and bathroom integrated exhaust system, and then determines the operating wind pressure and the total exhaust volume of the exhaust main unit, thereby obtaining the operating frequency of the exhaust main unit (implicitly determining the operating power). At the same time, by adjusting the valve openings of the kitchen air volume master control valve, the bathroom air volume master control valve, the kitchen flow power distribution valve on each floor and the bathroom flow power distribution valve on each floor, the exhaust volume of each powered-on floor is balanced, which can effectively alleviate the problems of poor exhaust and odor transfer in the middle and lower floors during the exhaust peak period.

[0075] The above briefly describes the kitchen and bathroom integrated exhaust control method provided by an embodiment of the present invention, and the relevant steps involved therein are specifically introduced below.

[0076] In an optional embodiment, the above step S104, based on the first preset air volume, the second preset air volume and the current working condition, determines the static pressure value inside the public exhaust duct on each floor, the total exhaust volume of the exhaust main unit, the operating air pressure of the exhaust main unit, the opening of the kitchen air volume master control valve and the opening of the bathroom air volume master control valve, specifically includes the following steps:

[0077] Step S1041, based on the first preset air volume, the number of range hoods turned on, the floors on which the range hoods are turned on, and the specifications of the kitchen public exhaust duct, determine the static pressure value inside the kitchen public exhaust duct on each floor and the total exhaust volume of the kitchen; and based on the second preset air volume, the number of ventilators turned on, the floors on which the ventilators are turned on, and the specifications of the bathroom public exhaust duct, determine the static pressure value inside the bathroom public exhaust duct on each floor and the total exhaust volume of the bathroom.

[0078] Specifically, the total exhaust volume of the kitchen is equal to the product of the first preset air volume and the number of range hoods turned on, and the total exhaust volume of the bathroom is equal to the product of the second preset air volume and the number of ventilators turned on. The following description is based on the example of determining the static pressure value inside the public exhaust duct of the kitchen on each floor, and the static pressure value inside the public exhaust duct of the bathroom on each floor is the same.

[0079] Given the first preset air volume, the number of range hoods turned on, the floors where the range hoods are turned on, and the specifications of the kitchen public exhaust duct, assuming that the building has 8 floors in total, and the number of range hoods turned on is 3, and the floors where the range hoods are turned on are 1st, 3rd, and 8th floors respectively, then using the assumed flow rate method, it is known that the air volume of each range hood when exhausting is the first preset air volume, then it is necessary to iteratively calculate the static pressure value inside the kitchen public exhaust duct on each floor under the first preset air volume starting from the 1st floor. First, based on the specifications of the kitchen public exhaust duct, it is possible to determine the extended resistance that the gas exhausted from the 1st floor needs to overcome when passing through the exhaust duct between the 1st and 3rd floors (related to the exhaust duct cross-sectional size, exhaust The roughness of the air duct wall is related to the air density). Next, calculate the confluence resistance when the gas discharged from the 1st floor merges with the gas discharged from the 3rd floor. Then calculate the extended resistance that the gas after confluence needs to overcome when passing through the exhaust ducts from the 3rd floor to the 8th floor. Finally, calculate the confluence resistance when the gas merges on the 8th floor. This can determine the static pressure value inside the public exhaust duct in the kitchens on each floor. Since the flow power distribution valve in the kitchens on the floors that are not turned on is in a closed state, it is only necessary to determine the static pressure value inside the public exhaust duct in the kitchens on the turned-on floors and the static pressure value inside the public exhaust duct in the kitchens on the top floor (used to determine the operating wind pressure of the exhaust main unit).

[0080] Step S1042, determining the total exhaust volume of the exhaust host based on the total exhaust volume of the kitchen and the total exhaust volume of the bathroom.

[0081] In the embodiment of the present invention, the total exhaust volume of the exhaust main unit is the sum of the total exhaust volume of the kitchen and the total exhaust volume of the bathroom.

[0082] Step S1043, determining a first extended-range resistance and a second extended-range resistance of the connected air duct based on the specifications of the connected air duct.

[0083] The first connecting air duct between the public exhaust duct of the top-floor kitchen and the exhaust main unit affects the wind pressure received by the public exhaust duct of the kitchen, and the second connecting air duct between the public exhaust duct of the top-floor bathroom and the exhaust main unit affects the wind pressure received by the public exhaust duct of the bathroom. Therefore, in order to determine the operating wind pressure of the exhaust main unit, it is necessary to calculate the first extended resistance and the second extended resistance of the connecting air duct according to the specifications of the connecting air duct, wherein the first extended resistance represents the resistance generated by the first connecting air duct between the public exhaust duct of the top-floor kitchen and the exhaust main unit, and the second extended resistance represents the resistance generated by the second connecting air duct between the public exhaust duct of the top-floor bathroom and the exhaust main unit.

[0084] Step S1044, determines the operating wind pressure of the exhaust main unit, the opening of the kitchen air volume master control valve and the opening of the bathroom air volume master control valve based on the static pressure value inside the public exhaust duct of the kitchen on each floor, the static pressure value inside the public exhaust duct of the bathroom on each floor, the first extended resistance and the second extended resistance.

[0085] In order to ensure that the lowest floor with range hoods turned on meets the first preset air volume, and the lowest floor with ventilators turned on meets the second preset air volume, after determining the static pressure value inside the public exhaust duct of the kitchens on each floor, the static pressure value inside the public exhaust duct of the bathrooms on each floor, the first extended resistance and the second extended resistance, it is necessary to further calculate the operating air pressure of the exhaust main unit, and determine the opening of the kitchen air volume master control valve and the bathroom air volume master control valve.

[0086] Specifically, the above step S1044 determines the operating wind pressure of the exhaust main unit, the opening of the kitchen air volume master control valve, and the opening of the bathroom air volume master control valve based on the static pressure value inside the public exhaust duct of the kitchen on each floor, the static pressure value inside the public exhaust duct of the bathroom on each floor, the first extended resistance, and the second extended resistance, and specifically includes the following steps:

[0087] Step S10441, determining the first wind pressure based on the static pressure value inside the public exhaust duct of the top-floor kitchen and the first extended-range resistance; and determining the second wind pressure based on the static pressure value inside the public exhaust duct of the top-floor bathroom and the second extended-range resistance.

[0088] First, the static pressure value inside the public exhaust duct of the top kitchen is summed with the first extended resistance to obtain the first wind pressure, and the static pressure value inside the public exhaust duct of the top bathroom is summed with the second extended resistance to obtain the second wind pressure.

[0089] Step S10442, when the first wind pressure is greater than the second wind pressure, the opening of the kitchen air volume master control valve is greater than the opening of the bathroom air volume master control valve, so that each range hood can obtain the first preset air volume, and each ventilator can obtain the second preset air volume; and the operating air pressure of the exhaust host is determined based on the first wind pressure.

[0090] Step S10443, when the first wind pressure is less than the second wind pressure, the opening of the kitchen air volume master control valve is less than the opening of the bathroom air volume master control valve, so that each range hood can obtain the first preset air volume, and each ventilator can obtain the second preset air volume; and the operating air pressure of the exhaust host is determined based on the second wind pressure.

[0091] Specifically, when determining the operating wind pressure of the exhaust main unit, it is also necessary to consider the target confluence resistance when the gases in the bathroom public exhaust duct and the kitchen public exhaust duct merge. If the first wind pressure is greater than the second wind pressure, then the first wind pressure is added to the target confluence resistance to obtain the operating wind pressure of the exhaust main unit under the current circumstances, and the opening of the kitchen air volume master control valve is greater than the opening of the bathroom air volume master control valve. This is because if the opening of the bathroom air volume master control valve is not reduced, the air volume reaching the bathroom public exhaust duct will be greater than the actual air volume required for exhaust.

[0092] If the first wind pressure is less than the second wind pressure, then the second wind pressure is added to the target confluent resistance to obtain the operating wind pressure of the exhaust main unit under the current circumstances, and the opening of the kitchen air volume master control valve is smaller than the opening of the bathroom air volume master control valve. If the opening of the small kitchen air volume master control valve is not adjusted, the air volume reaching the kitchen public exhaust duct will be greater than the actual air volume required for exhaust.

[0093] In an optional embodiment, the above step S106, based on the static pressure value inside the public exhaust duct on each floor, the total exhaust volume of the exhaust host and the operating wind pressure of the exhaust host, determines the operating frequency of the exhaust host, the valve plate opening of each kitchen flow power distribution valve and the valve plate opening of each bathroom flow power distribution valve, specifically includes the following steps:

[0094] Step S1061, determining the operating frequency of the exhaust main unit based on the preset fan power performance curve of the exhaust main unit, the total exhaust volume of the exhaust main unit and the operating wind pressure of the exhaust main unit.

[0095] Figure 7 A schematic diagram of a power performance curve of a fan when operating at partial frequency is shown. Under the premise that the total exhaust volume of the exhaust main unit and the operating air pressure of the exhaust main unit are known, the operating frequency of the exhaust main unit can be determined in combination with the preset fan power performance curve of the exhaust main unit.

[0096] Step S1062, determining a first target static pressure value of the range hood based on a first preset power performance curve and a first preset air volume of the range hood; and determining a second target static pressure value of the range hood based on a second preset power performance curve and a second preset air volume of the ventilator.

[0097] Each range hood and ventilator is provided with a corresponding preset power performance curve. The first target static pressure value of the range hood can be determined according to the first preset power performance curve of the range hood (characterizing the corresponding relationship between air volume and static pressure) and the first preset air volume; the second target static pressure value of the ventilator can be determined according to the second preset power performance curve of the ventilator (characterizing the corresponding relationship between air volume and static pressure) and the second preset air volume.

[0098] Step S1063, determining the valve plate opening of the kitchen flow power distribution valve on the first target floor based on the static pressure value inside the kitchen public exhaust duct on the first target floor, the first target static pressure value and the preset kitchen pipeline resistance.

[0099] Step S1064, determining the valve plate opening of the flow power distribution valve of the bathroom on the second target floor based on the static pressure value inside the public exhaust duct of the bathroom on the second target floor, the second target static pressure value and the preset bathroom pipeline resistance.

[0100] Specifically, the resistance of different valve plate openings of the (kitchen or bathroom) flow power distribution valve at a certain flow rate is determined in advance through experimental testing. Therefore, the resistance value that needs to be provided by the kitchen flow power distribution valve on the first target floor can be determined based on the static pressure value inside the public exhaust duct of the kitchen on the first target floor, the first target static pressure value and the preset kitchen pipe resistance (including aluminum foil duct resistance and fire damper resistance). Then, based on the correspondence between the resistance value and the valve plate opening determined in advance, the valve plate opening of the kitchen flow power distribution valve on the first target floor can be obtained; using the same calculation method, the valve plate opening of the bathroom flow power distribution valve on the second target floor can also be determined; wherein, the first target floor represents any floor among the floors where the range hood is turned on, and the second target floor represents any floor among the floors where the ventilator is turned on.
