Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an indoor exhaust system,

The present invention relates to a method of controlling an indoor exhaust apparatus and an air supply apparatus interlocked with the indoor exhaust apparatus, and more particularly, to a control method of an indoor exhaust apparatus capable of exhausting contaminated air in the room outdoors, To a room.

The kitchen hood, which is one of the kitchen appliances, is installed in the kitchen, and is used to prevent the air pollution in the kitchen by discharging the combustion gas, food odor and water vapor generated when the food is cooked in the kitchen to the outside.

Such a kitchen hood is installed in an upper portion of a kitchen appliance including a gas range, an electric range, and the like. The gas generated in the cooking appliance and the gas generated in cooking the food are discharged to the outside using an exhaust fan.

On the other hand, an exhaust fan is provided in the toilet to exhaust the odor and moisture (moisture) generated when using the toilet more quickly to the outside.

However, even when the kitchen hood is operated, a part of the combustion gas and food odor generated during cooking is diffused to the room such as a living room without being discharged to the outside by the exhaust fan, and the odor and water vapor (moisture) Even if the exhaust fan is operated, some of the odor and water vapor (moisture) is diffused into the room without being discharged to the outside.

In addition, when the exhaust fan is continuously operated to discharge polluted air to the outside, negative pressure is formed in the room, so that exhaust is not smoothly performed. If the exhaust fan is continuously operated in this state, noise and vibration are increased .

On the other hand, a method of increasing the capacity of the exhaust fan to expel the odor and water vapor (moisture) generated in the kitchen and the toilet more quickly can be considered. However, if the capacity of the exhaust fan is increased, the size of the exhaust fan becomes large, which results in a problem that installation space and cost are increased.

In addition, when the size of the exhaust fan is increased, power consumption during operation of the exhaust fan increases, resulting in an increase in electric charges, and vibration and noise are increased during operation of the exhaust fan, thereby failing to provide a comfortable living environment.

As a prior art in which a conventional kitchen hood is shown, Korean Utility Model Registration Utility Model No. 20-265992 is disclosed.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide an air conditioner, And an object of the present invention is to provide an indoor exhaust apparatus and a control method of the air supply apparatus interlocked with the indoor exhaust apparatus.

Further, if the exhaust efficiency is improved through the proper supply of air, the same performance as the conventional one can be exhibited even with a small-capacity exhaust device, thereby reducing the space and cost required for installation of the exhaust device, And it is an object of the present invention to provide an indoor exhaust apparatus and a control method of an air supply apparatus interlocked with the indoor exhaust apparatus, which can provide a pleasant indoor environment by reducing noise and vibration generated during operation of the exhaust apparatus.

It is another object of the present invention to provide an indoor exhaust apparatus capable of quickly and smoothly exhausting contaminated air by measuring the pollution degree of the indoor unit and operating the exhaust apparatus automatically, and a control method of the air supply apparatus interlocked therewith.

According to another aspect of the present invention, there is provided a method of controlling an indoor exhaust apparatus including the steps of: a) exhausting indoor air outdoors by an exhaust device operation signal; b) determining whether air supply to the room is required; and c) if the air supply is determined to be necessary, transmitting the air supply signal to the air supply unit such that air supply from the air supply unit to the room is performed.

In this case, d) determining whether the supply amount change is necessary after the supply of the supply air is performed for a predetermined time by the supply device; and e) if the supply amount variation is determined to be necessary, transmitting the supply amount adjustment signal to adjust the supply amount.

The exhaust device activation signal of step a) may be a signal input from a user; And a signal including environmental information of the room where the exhaust is performed.

The indoor environmental information may include indoor indoor air pollution detected by the indoor indoor air temperature sensing unit. When the indoor indoor air temperature is higher than the predetermined indoor air pollution degree, the indoor air temperature sensing unit may receive the exhaust operation signal.

The operating intensity of the exhaust device can be determined corresponding to the indoor pollution degree detected by the indoor environment sensing unit.

When the signal from the indoor environment sensing unit is received, the operation intensity of the exhaust device can be set to a predetermined value.

In the step b), it is possible to determine the necessity of the air supply by sensing the rotation speed (rpm) of the exhaust device.

In the step d), it is possible to determine the necessity of the variation of the supply amount by sensing the rotational speed (rpm) of the exhaust device.

If the sensed number of revolutions of the exhaust device is higher than the preset number of revolutions, it may be determined that there is a need for the supply of air or a variation of the supply amount.

If it is determined in step d) that the amount of supplied air is maintained or the amount of air supplied is decreased, if the sensed number of revolutions of the exhaust device is less than a predetermined number of revolutions; If the sensed number of revolutions of the exhaust device is higher than a predetermined number of revolutions, it is determined that the amount of supplied air needs to be increased; In the step (e), the supply amount adjustment signal may be transmitted so that the supply amount is adjusted according to the determined result.

In the step b) and the step d), it is possible to determine the necessity of the air supply by measuring the pressure difference between the inside of the exhaust pipe connected to the exhaust device and the room.

In this case, the pressure inside the exhaust pipe and the pressure in the room are respectively measured, a first pressure difference which is a difference between the pressure inside the exhaust pipe and the pressure in the room at the first time point at which the measurement is made is obtained, And a second pressure difference which is a difference between a pressure inside the exhaust pipe at a second time point of the intake pipe and a pressure in the inside of the room is determined and if the difference between the first pressure difference and the second pressure difference is larger than a set value, It can be judged that there is a need for change.

The air supply signal may be transmitted so that the amount of air supplied through the air supply device is equal to or less than the amount of exhausted air discharged by the air exhaust device when the air supply signal is transmitted in the step c).

If it is determined in step a) that the control unit is operating in a control mode other than the mode in which the air supply in step c) is performed in another indoor space other than the indoor space requiring the air supply, ) Step may be performed.

If the room is a toilet, the supply air can be directly controlled in the inside space of the toilet.

After the step c), if the room is a bathroom, a certain period of time has elapsed after the user has determined that the toilet has left the toilet, or until the odor sensed by the odor sensor becomes the set value or the humidity sensed by the humidity sensor becomes the set value It is possible to control the operation of the exhaust device and the stop of the supply of the indoor air after the operation of the exhaust device and the indoor air supply are maintained.

When the air supply in the step c) is performed, if the air is already supplied to the second indoor space other than the first indoor space requiring the air supply, the first indoor space It is possible to perform supply to the space.

A control method of an air supply apparatus according to the present invention includes the steps of: a) receiving an air supply signal from an air supply apparatus, and b) supplying air to the room in accordance with the air supply signal.

C) receiving a supply amount adjustment signal indicating that a supply amount change is required from the exhaust device; and d) adjusting a supply amount supplied to the room according to the received supply amount adjustment signal.

According to the present invention, in order to exhaust polluted air generated in a room such as a kitchen or a bathroom, it is necessary to determine the necessity of supplying air with the operation of the air exhaust device so that the air supply is automatically performed, While increasing the exhaust efficiency, the pollutant source can be quickly discharged to the outside.

In addition, when air is supplied into the room, the air is supplied at an optimum amount of air supply so that the air supply is prevented from being generated more than necessary, thereby preventing the contamination source from diffusing, And quick exhaust can be achieved.

In addition, since excessive negative pressure is prevented from being formed in the indoor space through the proper air supply, the exhaust efficiency is improved, so that the same performance as the conventional one can be exhibited even with the small capacity exhausting device, And it is possible to reduce the electricity cost required in the operation of the exhaust device and to reduce the noise and vibration generated in the exhaust device.

Further, the pollution degree of the room is measured and the exhaust device is automatically operated, so that the polluted air can be exhausted quickly and smoothly.

In addition, when air is supplied to the indoor space through which the air is exhausted by the exhaust device, if the indoor space other than the indoor space to which the air is to be supplied is already operating in the ventilation mode, the ventilation mode operation is terminated, If the mode is switched to the air supply mode for supplying air, a sufficient amount of air supply can be ensured and the exhaust efficiency can be improved.

In addition, when outside air is directly supplied to the inside of the toilet, the user can smoothly exhaust the odor and steam even when the toilet door is closed.

In addition, when the outdoor temperature is lower than the set temperature, the cold outdoor air is supplied to the toilet during the winter by heating after the heating, thereby preventing the user from feeling uncomfortable when using the toilet and preventing the water in the toilet from freezing, Can be prevented.

2 is a view showing a control configuration of an exhaust device and an air supply device according to the present invention;
3 is a flowchart showing a control method of an exhaust system according to the present invention.

Hereinafter, the exhaust system of the present invention and the control method of the air supply system interlocked with the exhaust system of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, an exhaust system according to the present invention and a control structure of an air supply device interlocked with the exhaust system will be described.

The exhaust devices 110 and 120 of the present invention are controlled in cooperation with the air supply device 200.

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 operated manually by a user's selection or may be manually operated by the first indoor environment sensing part 310 and the second indoor environment sensing part 320 And may be configured to be automatically activated based on the detected indoor environment information. The indoor environment information may be pollution degree of indoor air, for example.

As an example of a method of automatically activating the second exhaust device 120, the second exhaust device 120 is automatically activated by a detection signal of an odor sensor (not shown) . ≪ / RTI >

Further, the second exhaust device 120 can be configured to automatically operate by a detection signal from a toilet humidity sensor (not shown) that can detect the humidity inside the toilet to exhaust moisture from the inside of the toilet after showering have.

In order to determine whether the indoor air is discharged to the outside due to the operation of the first exhaust device 110 and the second exhaust device 120 and a negative pressure higher than a set value is formed in the indoor space, The first pressure measurement unit 312 and the second pressure measurement unit 322 may be included in the first pressure measurement unit 311 and the second pressure measurement unit 321, respectively.

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 first differential pressure measuring unit 312 measures the pressure difference between the inside of the exhaust pipe 111 connected to the first exhaust unit 110 and the indoor 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 121 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 (111, 121) and the pressure inside the room are measured for a predetermined time. A first pressure difference which is a difference between the pressure inside the exhaust pipe (111, 121) and the pressure in the room at a first point in time at which the measurement is performed is obtained. Then, a second pressure difference, which is a difference between the pressure inside the exhaust pipe (111, 121) and the pressure in the room at a second point of time that has elapsed from the first point of time, 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 first exhaust device 110 and the second exhaust device 120 include a communication function and are communicated with the communication unit 230 of the air supply device 200 to communicate with the first and second exhaust devices 110, To the air supply device (200).

The air supply device 200 may be configured as an air supply module provided in the air conditioner. In this case, outdoor air may be supplied to the indoor unit 100 in accordance with the operation information received from the first and second exhaust devices 110, A communication unit 230 for communicating with the exhaust units 110 and 120, and an air supply blower 210 for supplying outdoor air to the room.

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,

The discharge ports 203, 204, 205, 206 and 207 may be provided on the ceiling or 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. 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.

2, 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 devices 110 and 120 are operated to receive the exhaust device activation signal and to exhaust the room air to the outside.

In this case, the exhaust device activation signal may be composed of a signal input from the user. That is, when the user presses the switch to start the exhaust apparatuses 110 and 120, the exhaust apparatuses 110 and 120 can be operated by the switch signal.

In addition, the exhaust device activation signal 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 air 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, the exhaust devices 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 device (11, 120) is automatically operated, so that contaminated air can be exhausted quickly and smoothly.

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, it is determined 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 sensed by the rotational speed measuring units 311 and 321 and the pressure difference between the inside and the inside of the exhaust pipes 111 and 121 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 operation proceeds to step S40. Otherwise, the operation of the exhaust devices 110 and 120 is maintained until the air supply to the indoor space is determined.

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 air supply to the indoor space is necessary, and the exhaust devices 110 and 120 transmit the air supply signal to the air supply device 200. [

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. Therefore, the air supply signal is transmitted so that the amount of air supplied through the air supply device 200 is equal to or less than the amount of air exhausted to the outside by the first exhaust device 110, thereby preventing the contaminated air from diffusing.

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.

The air supply device 200 operates the air supply blower 210 according to the received air supply signal to supply outdoor air to the room.

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 S50, it is determined whether or not the amount of air supplied to the indoor space needs to be changed after the air supply is performed by the air supply device 200 for a predetermined time.

In this case, the necessity of variation of the supply amount is determined by detecting the rotation speed (rpm) of the exhaust apparatuses 110 and 120 by the rotation speed measurement units 311 and 321 or by measuring the pressure difference between the inside of the exhaust pipes 111 and 121 and the indoor space, 312, 322), and can judge from the sensed number of revolutions or the 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 necessary to increase the amount of supplied air, because the amount of supplied air is greater than the amount of supplied air in step S40.

In step S60, the air supply amount adjustment signal is transmitted to the air supply device 200 according to the determined necessity of the air supply amount variation.

The supply device 200 adjusts the supply amount according to the received supply amount adjustment signal.

It is determined whether or not the supply end condition is satisfied in step S70. 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, 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 leaves 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 leaves the toilet can be detected from a 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, it may be configured to generate a signal or an alarm that the user needs to change the supply or supply amount. In this case, the signal or alarm to change the supply or supply amount is required to be displayed on the display or to generate a sound. The signal or alarm may be generated by the exhaust devices 110 and 120, .

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.

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.
