The exhaust devices 110 and 120 may include a first exhaust device 110 (a kitchen hood) provided in the kitchen and operated when cooking food, and a second exhaust device 120 installed in the toilet and operated when the toilet is used.

In this case, the room where the exhaust apparatuses 110 and 120 are installed may include all places where contaminated air such as gas or odor is generated including a kitchen and a toilet, and the number of the exhaust apparatuses may be additionally set as needed .

The first exhaust device 110 and the second exhaust device 120 may be manually operated by the user's choice or may be automatically activated based on the indoor environment information. The indoor environment information may be pollution degree of indoor air, for example.

When the exhaust apparatuses 110 and 120 are manually operated, the exhaust apparatus operation information may be a signal input from the user through the input units 117 and 127, and the exhaust apparatus operation information may be input by the user, When the signals are received by the receiving units 112 and 122, the exhaust devices 110 and 120 are activated.

When the exhaust apparatuses 110 and 120 are automatically operated, the exhaust apparatus operation information may be a signal sensed by the indoor environment sensing units 310 and 320 that sense environmental information of the room where the exhaust is performed, The exhaust apparatuses 110 and 120 are activated when the indoor environment detection units 310 and 320 receive the exhaust system operation information from the exhaust system operation information receiving units 112 and 122, respectively.

The indoor environment sensing units 310 and 320 include a first indoor environment sensing unit 310 for sensing an indoor environment for operating the first exhaust unit 110 and a second indoor environment sensing unit 310 for operating the second exhaust unit 120. [ And a second indoor environment sensing unit 320 for sensing an indoor environment.

The first indoor environment sensing unit 310 or the second indoor environment sensing unit 320 senses the smell or humidity, and when the sensed signal is received by the exhaust device 110 or 120, (110, 120) are automatically operated.

The air supply necessity determination sections 113 and 123 determine the necessity of the air supply based on the information received from the rotation number measurement sections 311 and 321 for measuring the number of revolutions of the exhaust devices 110 and 120, It is possible to determine the necessity of the supply of air based on the information received from the differential pressure measuring units 312 and 322 that measure the pressure difference between the inside of the exhaust pipe and the room.

The rotational speed measuring units 311 and 321 are arranged such that the indoor air is discharged to the outside due to the operation of the first exhaust device 110 and the second exhaust device 120 so that a sound pressure higher than a set value is formed in the indoor space, A first rotational speed measurement unit 311 for measuring the rotational speed of the first exhaust unit 110 and a second rotational speed measurement unit 313 for measuring the rotational speed of the second exhaust unit 120, (321).

The first rotational speed measuring unit 311 and the second rotational speed measuring unit 321 are connected to the first rotational speed measuring unit 311 and the second rotational speed measuring unit 321 at a rotational speed rpm at which the fans of the first and second exhaust apparatuses 110, . If the indoor air is exhausted to some extent and the sound pressure of the indoor space is severely formed, the number of rotations of the exhaust devices 110 and 120 increases. If the number of revolutions of the fan is increased to a predetermined value or higher, the negative pressure is severely formed in the indoor space, and the exhaust does not smoothly proceed, so that it can be determined that the air supply is necessary.

The differential pressure measuring units 312 and 322 may include a first differential pressure measuring unit 312 and a second differential pressure measuring unit 322. The first differential pressure measuring unit 312 measures the pressure difference between the inside of the exhaust pipe 118 connected to the first exhaust unit 110 and the inside space when the fan of the first exhaust unit 110 rotates . When the fan of the second exhaust device 120 rotates, the second differential pressure measuring part 322 measures the pressure difference between the inside of the exhaust pipe 128 connected to the second exhaust device 120 and the pressure difference ). If it is determined that the differential pressure is greater than the set value and the negative pressure in the indoor space is severely formed, the exhaust does not proceed smoothly, so that it can be determined that the air supply is necessary.

It is also possible to determine the state of sound pressure from a change in pressure over a certain period of time. That is, the pressure inside the exhaust pipe (118, 128) and the pressure inside the room are measured for a predetermined time. A first pressure difference which is a difference between a pressure inside the exhaust pipe (118, 128) and a pressure in the room at a first point in time at which the measurement is made is obtained. Then, a second pressure difference, which is a difference between the pressure inside the exhaust pipe (118, 128) and the pressure in the room at a second time point after a lapse of a predetermined time from the first time point, is obtained. If the difference between the first pressure difference and the second pressure difference is larger than the set value, the negative pressure is gradually formed as the time elapses, so that the exhaust does not proceed smoothly, so that it can be determined that the air supply is necessary. If the difference between the first pressure difference and the second pressure difference is smaller than the set value, the exhaust gas smoothly progresses and the negative pressure is not formed so badly that it can be determined that the air supply is not necessary.

The air supply information generating units 114 and 124 may be configured to generate an alarm notifying the user that air supply is required or to supply the air supply to the air supply apparatus 200 when the air supply necessity determination units 113 and 123 determine that there is a need for air supply And the like. In this case, the supply information may be one of an alarm or an air supply signal.

The alarm generated by the supply information generators 114 and 124 may be an alarm sound indicating that the supply of the air is necessary or may include character information indicating that supply of air to the display units 116 and 126 is required.

When an alarm is generated in the air supply information generators 114 and 124, the user can operate the air supply device 200 to supply air to the room where air supply is required.

The first exhaust device 110 and the second exhaust device 120 communicate with the air supply device 200 when the air supply information generators 114 and 124 transmit the air supply signal to the air supply device 200 And communication units 115 and 125, respectively. The communication units 115 and 125 of the exhaust units 110 and 120 communicate with the communication unit 230 of the air supply unit 200 to transmit the air supply information to the air supply unit 200.

The air supply device 200 may include an air supply module provided in the air conditioner and may control the air supply mode to supply outdoor air to the indoor according to the air supply information, And an air supply blower 210 for blowing air.

The control unit 240 includes an air supply information receiving unit 241 for receiving air supply information indicating that air supply is required to the room, and a control unit 240 for receiving the air supply information from the air supply information receiving unit 241, And an air supply driving section 242 for driving the blower 210.

When the air supply apparatus 200 is configured as an air conditioner such as an air conditioner, a cooling / heating apparatus, and a ventilation apparatus, a function of ventilation, air cleaning, dehumidifying, humidifying, cooling and heating modes may be provided including an air supply mode. And an exhaust blower 220 for exhausting the air outdoors.

In addition, the air supply device 200 may be provided integrally with the exhaust devices 110 and 120. For example, the one side of the kitchen hood may be provided with an exhaust fan for exhausting indoor air to the outside, and the other side of the kitchen hood may be provided with an air supply fan for supplying outdoor air to the room.

The outdoor air sucked by the air supply fan 210 of the air supply device 200 flows to the distributor 202 through the duct 201 and the indoor space of the living room, And the air distributed by the distributor 202 is supplied to the respective indoor spaces through the discharge ports 203, 204, 205, 206, 207,

In the distributor 202, a plurality of dampers (not shown) may be provided to distribute the air flowing through the duct 201 to the respective indoor spaces. Therefore, when the damper corresponding to the indoor space to be supplied is opened, the air is supplied through the discharge openings 203, 204, 205, 206, 207, 208 connected thereto.

The discharge ports 203, 204, 205, 206, 207 and 208 may be provided on the ceiling or may be provided on the floor. In particular, in the case of a kitchen, a discharge port may be provided at the bottom of a position adjacent to the first exhaust device 110 so that air is discharged upward. Further, even when the discharge port is provided in the ceiling, air is supplied toward the floor of the toilet or the kitchen, thereby effectively preventing contaminated air from diffusing into another indoor space. In addition, it is not limited to the ceiling and the floor, but can be installed at other positions as long as outdoor air can be supplied to the room.

Although the duct 201 is not connected to the air supply device 200 and the air supply device 200 is installed in the room and the air supply device 200 is connected to the air supply device 200, The air supply may be performed through the air supply line.

1, the air supplied from the air supply device 200 is distributed to the respective indoor spaces by the distributor 202. However, the air supplied from the air supply device 200 may flow through the distributor 202 (Not shown) so as to be supplied to a place where only air supply is required, such as a toilet or a dress room.

In addition, the air to be supplied may be configured to be supplied to the space between the toilet and the adjacent indoor space (living room, room), or may be configured to be supplied directly to the inside space of the toilet by connecting an air supply duct to the ceiling of the toilet It is possible. In the case of direct supply to the inside space of the toilet, the inside of the toilet can be smoothly discharged even when the toilet door is closed when using the toilet.

The first indoor environment sensing unit 310 may be a first pollution sensing unit that senses whether the kitchen air is polluted. The second indoor environment sensing unit 320 may include a second indoor environment sensing unit 320, And a contamination detection unit. The first indoor environment sensing unit 310 and the second indoor environment sensing unit 320 may be configured to detect contaminants such as gas contained in air. In this case, Information can be transmitted to the exhaust apparatuses 110 and 120. In the exhaust apparatuses 110 and 120, it is possible to determine the degree of pollution of the air based on the information of the received pollutants, and the operation and the intensity of the exhausts 110 and 120 can be determined according to the degree of pollution of the air.

In an example of the second indoor environment sensing unit 320, an odor sensor (not shown) capable of sensing a smell generated when a user defecates and a humidity sensor (not shown) And a toilet humidity sensor (not shown) that can detect the humidity can be provided.

In this case, the odor sensor and the toilet humidity sensor are separately provided from the second exhaust device 120 and the air supply device 200, and can be installed at an appropriate position of the toilet by the user.

If the odor sensor is separately installed in the toilet, the second exhaust device 120 can be automatically operated and exhausted every time the sensed odor reaches a predetermined value or more.

A control method of the exhaust system of the present invention constructed as described above will be described with reference to Fig. The first exhaust device 110 and the second exhaust device 120 can be operated by the same method.

In step S10, the exhaust device operation information for operating the exhaust devices 110 and 120 is received by the exhaust device operation information receiving unit 112. [

In this case, the exhaust apparatus operation information may be constituted by a signal input from the user. That is, when the user presses a switch of the input units 117 and 127 to operate the exhaust apparatuses 110 and 120, the exhaust apparatuses 110 and 120 can be operated by the switch signal.

Also, the exhaust operation information may be a signal received from the indoor environment sensing units 310 and 320 to operate the exhaust devices 110 and 120 when the indoor pollution degree sensed by the indoor environment sensing units 310 and 320 is equal to or higher than the set pollution degree.

That is, when the user senses that the user is defecated by the smell detected by the smell sensor at the time of user's defecation, a control signal is transmitted so that the operation and the operation intensity of the second exhaust device 120 are automatically determined by the detected signal can do.

Further, since the humidity inside the toilet is high after the user has showered, it is necessary to discharge the moisture outdoors. Accordingly, if the humidity sensor detects humidity above the humidity set by the toilet humidity sensor, the control unit can send a control signal to automatically determine whether the second exhaust device 120 is in operation or not according to the detection signal.

In step S20, when the exhaust apparatus operation information is received in the exhaust apparatus operation information receiving units 112 and 122, the exhaust apparatuses 110 and 120 are activated.

In this case, it is possible to determine the operating intensity of the exhaust apparatuses 110 and 120 according to the indoor pollution degree detected by the indoor environment detecting units 310 and 320. That is, when the indoor pollution degree detected by the indoor environment sensing units 310 and 320 is severe (that is, when the value sensed by the odor sensor is high or the humidity sensed by the toilet humidity sensor is high) (rpm), and when the indoor pollution degree is not severe (i.e., the value sensed by the odor sensor is low or the humidity sensed by the toilet humidity sensor is low), the fan is operated at a lower rotational speed (rpm) Lt; / RTI >

In addition, when the indoor pollution degree detected by the indoor environment sensing units 310 and 320 is higher than the set value regardless of the indoor pollution degree, the fan may be rotated at a predetermined number of revolutions.

As described above, the pollution degree of the room is measured and the exhaust devices 110 and 120 are automatically operated, so that polluted air can be quickly and smoothly discharged.

Further, the number of revolutions of the fan may be manually set by user selection. It may be set to rotate at a high rotation speed from the beginning or may be set to rotate at a low rotation speed from the beginning.

In step S30, the air supply necessity determination units 113 and 123 determine whether air supply to the indoor space is necessary.

When the exhaust apparatuses 110 and 120 are operated, indoor air is discharged to the outside, and the indoor space becomes a negative pressure state. If the exhaust is continued, the indoor space is formed with a heavy sound pressure, so that the exhaust is not smoothly performed. If it is detected that the sound pressure is severely formed, it can be determined that air supply to the indoor space is necessary.

Whether or not sound pressure is formed in the indoor space is detected by the rotational speed measuring units 311 and 321 and the pressure difference between the inside and the inside of the exhaust pipes 118 and 128 by the differential pressure measurement (312, 322), and can judge from the sensed number of revolutions or the differential pressure.

If it is determined that air supply is necessary, the process proceeds to step S40, and otherwise, the exhaust devices 110 and 120 are maintained in an operating state until it is determined that supply of air to the indoor space is necessary.

If the air supply unit 200 (air conditioner) is already operating in the ventilation mode when the exhaust apparatuses 110 and 120 start to operate, the operation of the ventilation mode is stopped and the air supply to the kitchen or toilet, And switching to an air supply mode for performing the operation. When the control is performed in this way, a sufficient supply amount can be secured, and the exhaust efficiency can be improved.

When the second exhaust device 120 is operated while the first exhaust device 110 is operated to supply air to the kitchen, which is the first indoor space, the air is supplied to the toilet, which is the second indoor space, As shown in FIG. On the other hand, when the first exhaust device 110 is operated while supplying air to the toilet, air may be supplied to the kitchen while maintaining air supply to the toilet.

In step S40, it is determined that supply of air to the indoor space is necessary, and the supply information generator 113 of the exhaust apparatuses 110 and 120 generates supply information.

The air supply information generators 114 and 124 generate an alarm that the air supply is required or transmit the air supply signal to the air supply apparatus 200 through the communication units 115 and 125.

In step S50, the air supply device 200 is operated.

The supply device 200 is activated by a signal input by a user through an input unit (not shown) provided in the supply device 200 according to the generation of the supply information, When the air supply information is received by the air supply information receiving unit 241, the air supply apparatus 200 is operated.

The air supply driving part 242 of the air supply device 200 drives the air supply blower 210 to supply outdoor air to the room.

In the case of supplying outdoor air to the room, it is preferable that a weak sound pressure is formed in the indoor space in which the exhaust devices 110 and 120 are running, in order to prevent the contaminated air from diffusing.

For example, when cooking is performed in the kitchen, the first exhaust device 110 is operated and the outdoor air supplied from the air supply device 200 is supplied to the kitchen through the discharge opening 204 provided in the kitchen. In this case, if the amount of air supplied is larger than the amount of exhaust, the contaminated air in the kitchen space may not be exhausted to the outside through the first exhaust unit 110, but a part of the air may be diffused into the living room. Accordingly, by supplying the air supply information such that the amount of air supplied through the air supply device 200 is equal to or less than the amount of exhausted air discharged to the outside by the first exhaust device 110, the contaminated air can be prevented from being diffused.

In the case of supplying air to the room, contaminated air can be diffused if the air is supplied at a supply amount higher than necessary, and if air is supplied at a too low supply amount, the exhaust efficiency is lowered and rapid exhaustion is not achieved.

Therefore, if the air supply is performed at an optimum supply amount so as to form an appropriate sound pressure, it is possible to prevent the contamination from spreading due to no more than necessary supply, and at the same time, A smooth exhaust can be achieved.

Also, since the exhaust efficiency can be improved through proper supply of air, it is possible to reduce the capacity of the exhaust devices 110 and 120, so that the space and cost required for installing the exhaust devices 110 and 120, Noise and vibration can be reduced.

If the discharge port 207 is located in the living room, which is an indoor space outside the toilet, air is not supplied to the inside space of the toilet even if the user supplies air to the living room when the toilet is used while the toilet door is closed. Therefore, in this case, the air is directly supplied to the internal space of the toilet through the discharge port 207 connected to the ceiling of the toilet, so that the exhaust of the second exhaust system 120 can be smoothly performed even when the toilet door is closed. Of course, the toilet door may be closed or open, and the air supply to the inside of the toilet and the supply of air to the indoor space outside the toilet may be selected or simultaneously performed.

In the case where the air supply unit 200 is provided with an air supply duct so that the air supplied through the air supply unit 200 can be directly supplied to a place requiring only supply of air such as a toilet or a dress room without passing through the distributor 202, It is also possible to maintain the operating state of the mode and independently supply air to the bathroom or dressroom where the air supply is required.

In winter, when the air supplied to the room is heated by operating the heating unit (not shown) in the air supply mode in the air supply mode, the room temperature can be prevented from falling due to the indoor air supply of the cold air, thereby maintaining a warm indoor environment. To this end, an outdoor temperature sensor for detecting the outdoor temperature may be further provided. When the temperature sensed by the outdoor temperature sensor is lower than the set temperature, the heating unit may be operated in the air supply mode. In particular, when cold outdoor air is supplied to the toilet in winter, the toilet may feel uncomfortable when using the toilet, or water in the toilet may freeze. Therefore, it is preferable to supply air heated by the heating unit to prevent this. The heating of the air supply air may be performed using a heating unit provided inside the air supply unit 200 or a heater provided in an air supply duct provided outside the air supply unit 200 to heat the air supply air.

In step S60, it is determined whether or not the supply amount variation is necessary for the indoor space after the air supply is performed for a predetermined time by the air supply device 200. [

In this case, it is possible to determine the necessity of variation of the supply amount by the exhaust apparatuses 110 and 120.

The rotational speed measuring units 311 and 321 detect the rotational speed rpm of the exhaust apparatuses 110 and 120 or the pressure difference between the inside of the exhaust pipes 111 and 121 and the inside space is sensed by the differential pressure measuring units 312 and 322, It is possible to judge the necessity of fluctuation of the supply amount from the detected number of revolutions or differential pressure.

When the necessity of variation of the supply amount is determined using the number-of-revolutions measuring units 311 and 312, the current supply amount can be controlled to be maintained if the sensed number of revolutions is less than the predetermined first number of revolutions. If the detected number of revolutions is much lower than the first number of revolutions in some cases, the amount of supplied air is larger than necessary, so that it can be determined that the amount of supplied air needs to be reduced. If the detected number of revolutions is higher than the predetermined second number of revolutions, the exhaust is not smoothly performed. Therefore, it is judged that an increase in the amount of supply is required because a greater amount of supply is required than the amount of supply performed in step S50.

The supply amount change necessity determination may be performed by the control unit 240 of the air supply device 200 based on the information received from the revolution number measurement units 311 and 321 and the differential pressure measurement units 312 and 322. [

In step S70, the supply amount adjustment information is generated in accordance with the determined necessity of the supply amount variation.

The supply amount adjustment information may be an alarm to inform the user that the supply amount adjustment is necessary or may be configured to transmit a supply amount adjustment signal to adjust the supply amount to the supply device 200. [

The air supply apparatus 200 may adjust the air supply amount according to a signal input through the input unit by recognizing that the user needs to adjust the air supply amount from the alarm and may receive the air supply information from the air exhaust apparatuses 110 and 120 The supply amount can be adjusted based on the supplied supply amount adjustment information.

The air supply driving unit 242 adjusts the driving of the air supply blower 210 so that the air supply amount is changed according to the air supply amount adjustment information.

It is determined whether or not the supply end condition is satisfied in step S80. If the supply end condition is satisfied, the supply mode ends, otherwise the supply mode continues.

In this case, the air supply termination condition stops the operation of the exhaust apparatuses 110 and 120 when the indoor pollution degree detected by the indoor environment detection units 310 and 320 becomes less than the set value and the pollution source is removed or the air pollution degree becomes lower than an appropriate level.

When the second exhaust device 120 is configured to operate automatically as described above, the exhaust and supply of air may be terminated after the exhaust and supply of air are continued for a predetermined period of time even after the user finishes using the toilet. The predetermined time may be a predetermined time or may be configured such that when the odor sensed by the odor sensor is below a certain level or when the humidity sensed by the bathroom humidity sensor is below a certain level, have. In this case, whether or not the user has finished using the toilet can be detected based on whether or not the user leaves the toilet from the toilet entrance sensor (not shown). The toilet entrance / exit sensor may be an infrared sensor for detecting a human body heat.

The first indoor environment sensing unit 310, the second indoor environment sensing unit 320, the first rotation speed measurement unit 311, the second rotation speed measurement unit 321, the first differential pressure measurement unit 312, And the second differential pressure measuring unit 322 are connected to the exhaust apparatuses 110 and 120. However, the configurations are connected to the air supply apparatus 200 to measure the indoor environment information, the rotational speeds of the exhaust apparatuses 110 and 120, May be configured such that the pressure information of the pressure sensor 230 is received by the control unit 240 through the communication unit 230 of the air supply device 200. In this case, it is possible to judge whether the supply device 200 needs supply of air and the necessity of fluctuation of the supply amount. For the remaining control methods, the above-described control method can be similarly applied.

On the other hand, if it is detected that there is a necessity of the supply or variation of the supply amount, a signal or an alarm is generated to the user that the supply or supply amount fluctuation is necessary. In this case, the signal or alarm may be displayed on the display or generated by the user, thereby causing the user's attention. The signal or alarm may be generated in the exhaust apparatus 110, 120 or may be generated in the air supply apparatus 200.

When the user sees or hears the supply or supply amount fluctuation necessity signal or alarm, he or she may directly operate the supply device 200 to change the supply amount, change the supply amount, or open the window to supply or change the supply amount .

When the supply of air is performed by the user or the amount of supplied air is changed, the number of revolutions of the exhaust devices 110 and 120 is sensed by the rotational speed measuring units 311 and 312 or the differential pressure between the exhaust pipe and the room is measured by the differential pressure measuring units 312 and 3220 .

The necessity of fluctuation of the supply amount is determined again from the detected number of revolutions or the pressure difference. If it is determined that there is a need for further fluctuation of the supply amount, the user may again generate the supply amount fluctuation necessary signal or alarm.

According to the above-described structure, when the indoor air is supplied to the indoor space together with the operation of the exhaust devices 110 and 120 in order to exhaust the polluted air generated in the room such as a kitchen or a toilet, The exhausting efficiency can be increased and the pollutant source can be quickly discharged to the outside.

Referring to FIG. 4, a control method of the exhaust device and the air supply device according to another embodiment of the present invention will be described. In describing the control method of FIG. 4, only the difference among the control methods shown in FIG. 3 will be described, and the description of the remaining common parts will be omitted.

In step S110, when the user is cooking or using the toilet, the exhaust devices 110 and 120 are activated.

In step S120, it is determined that supply of air to the indoor space is required, and the supply information generator 113 of the exhaust apparatuses 110 and 120 generates supply information.

In step S130, which of the plurality of discharge ports (203, 204, 205, 206, 207, 208) is selected to be supplied through the discharge port and the corresponding damper is opened to supply the selected discharge port.

When the first exhaust device 110 is operated, the supply air is supplied through one or more outlets of the discharge outlets 203, 204, 206, 207, 208 excluding the discharge outlets 205 closest to the first exhaust device 110 out of the plurality of outlets 203, 204, 205, 206, 207, .

If air is supplied through the discharge port 205 closest to the first exhaust device 110, a part of the contaminated air can be diffused to the living room, which is an indoor space near the kitchen, without being discharged outdoors through the exhaust pipe 118 . Therefore, the air is supplied through the discharge port located farther than the discharge port 205 without supplying air through the discharge port 205 closest to the first discharge device 110, so that the contaminated air is diffused into the living room as the adjacent indoor space .

In this case, through one or more outlets of the plurality of outlets 203 and 204 provided in the living room, which is a space communicating with the kitchen, which is an indoor space in which the first exhaust unit 110 is located, of the remaining outlets 203, 204, 206, 207 and 208 excluding the nearest outlets 205, So that supply of air can be performed.

The control unit 240 receives position information of the exhaust devices 110 and 120 and position information of the discharge ports 203, 204, 205, 206, 207 and 208. From this positional information, the relative distances between the exhaust devices 110 and 120 and the respective discharge ports 203, 204, 205, 206, 207 and 208 can be calculated. Information on the relative distances between the exhaust devices 110 and 120 and the respective discharge ports 203, 204, 205, 206, 207 and 208 may be set in advance in the order of distances. Further, when a plurality of discharge ports are provided in the space communicating with each other, information on the positional relationship between the respective indoor spaces and the discharge ports may be inputted in advance.

From this positional information, it is possible to supply air through the discharge port 204, which is the longest distance from the first exhaust device 110, among the discharge ports 203 and 204 provided in the living room communicating with the kitchen. When air is supplied through the discharge port 204, which is the longest distance from the first exhaust device 110, the airflow of the air discharged from the discharge port 204 surrounds the space around which the kitchen and the living room are connected, It is possible to prevent the contaminated air in the living room from diffusing into the living room.

In addition, when the first exhaust device 110 is operated, indoor air is discharged to the outside, and the indoor space becomes a negative pressure state. If the exhaust is continuously performed and sound pressure is severely formed in the indoor space, In this state, when the first exhaust device 110 is continuously operated, noise and vibration are generated. Therefore, when the first exhaust device 110 is operated, if the air is supplied through the discharge port 204, the negative pressure is prevented from being formed in the kitchen space, so that the exhaust gas is smoothly discharged. Can be prevented.

The air is supplied through the discharge port 204 farthest from the first discharge device 110 and simultaneously supplied through the discharge port 205 closest to the first discharge device 110 It is possible. When the air is supplied from the two outlets 204 and 205, the negative pressure is prevented from being formed in the kitchen space due to the air supply from the air outlet 205 near the first exhaust unit 110, . Also, by supplying air through the discharge port 204 located far away from the first exhaust device 110, contaminated air can be prevented from diffusing from the kitchen space into the living room.

In the meantime, the air is directly supplied to the inner space of the toilet through the discharge port 208 connected to the ceiling of the toilet, so that the exhaust of the second exhaust device 120 can be smoothly performed even when the toilet door is closed. In this case, the toilet door may be closed or open, and the air supply to the inside of the toilet and the supply of air to the indoor space outside the toilet may be selected or simultaneously performed.

In step S140, the supply amount supplied through the discharge port is determined.

As the distance between the first exhaust device 110 and the discharge ports 203 and 204 through which the air is supplied from the first exhaust device 110 is greater, the amount of air supplied is preferably increased in order to prevent the contaminated air from being diffused. Accordingly, the amount of supply from the discharge port 204 located farthest from the first exhaust device 110 is the largest, the amount of supply from the discharge port 203 located next to the discharge port 203 is the next largest, So that the amount of air supplied to the engine can be minimized.

If the air is simultaneously supplied through the discharge port 205 closest to the discharge port 204 farthest from the first discharge device 110, the supply amount at the discharge port 204 farthest from the discharge port 204 is the closest It is preferable that the amount of supply from the discharge port 205 is larger than the supply amount. If the amount of air supplied from the nearest discharge port 205 is large, the contaminated air in the kitchen is more likely to diffuse into the living room. Therefore, it is preferable that the amount of air supplied to the discharge port 205 is determined so as to allow the air to be exhausted smoothly Do. In addition, the supply amount through the discharge port 204 at the farthest position is preferably larger than the supply amount at the discharge port 205 for preventing the contaminated air from being diffused. In this case, the supply amounts at the two discharge ports 204 and 205 are adjustable by adjusting the opening degree of the damper for supplying air to the respective discharge ports.

In step S150, the air supply blower 210 is operated in accordance with the supply amount determined in the step S150. If the operation of the air supply blower 210 is continued for a predetermined time, the flow advances to step S160.

In step S160, it is determined whether or not the supply end condition is satisfied. Here, the air supply termination condition may be a case where a signal indicating that the exhaust devices 110 and 120 are stopped is received. As a result of the determination, if the supply end condition for terminating the supply is satisfied, the supply mode is terminated. Otherwise, the supply state is maintained.

According to the above-described configuration, when the air in the kitchen or the toilet is contaminated and the air is exhausted by the exhaust devices 110 and 120 and the air is supplied by the air supply device 200, the air is discharged from the exhaust devices 110 and 120 So that contaminated air can be prevented from diffusing into other spaces in the room, and at the same time, the exhaust efficiency can be improved and a pleasant indoor environment can be provided.

As described above, the present invention is not limited to the above-described embodiments, and various changes and modifications may be made without departing from the scope of the present invention as defined in the appended claims.
