It may be configured to include flow paths (110, 120, 130, and 140).

Accordingly, the outdoor air flowing into the integrated air supply passage 100 is distributed to each room (S1, S2, and S3) through the at least one room air supply passage (110, 120, 130, and 140), and each room (S1, S2, and S3) The maximum air supply amount for each room (S1, S2, S3) can be formed in proportion to the number of air supply passages (110, 120, 130, 140) in each room connected to.

For example, one air supply passage (110; 120) may be connected to the bedroom (S1) and the kitchen (S), and two air supply passages (130, 140) may be connected to the living room (S3).

In other words, a more comfortable indoor environment can be achieved by distributing twice the amount of air supplied to the bedroom (S1) and the kitchen (S) to the living room (S3), which is larger and frequently used by a large number of family members.

The at least one air supply passage (100, 110, 120, 130, 140) may be provided with at least one air supply fan (101) that sucks in outdoor air and flows it indoors.

In addition, each room (S1, S2, S3) is connected to at least one exhaust passage 200 that exhausts indoor air to the outdoors.

The at least one damper (10, 11, 12, 13, 14) includes an integrated damper (10) that adjusts the opening degree of the integrated air supply passage (100), and an integrated damper (10) that controls the opening degree of the respective air supply passages (110, 120, 130, and 140). It may be configured to include at least one of the dampers 11, 12, 13, and 14.

The at least one damper (10, 11, 12, 13, 14) may be collectively controlled by the control unit 40 to collectively adjust the opening degree of the at least one air supply passage (100, 110, 120, 130, 140). there is.

Accordingly, the air supply can be performed or stopped simultaneously in the plurality of rooms (S1, S2, and S3), and the same amount of outdoor air can be supplied to each room air supply passage (110, 120, 130, and 140).

In addition, the at least one damper (10, 11, 12, 13, 14) may be individually controlled by the control unit 40 to individually adjust the opening degree of the at least one air supply passage (100, 110, 120, 130, 140). there is.

Accordingly, air supply may be performed or stopped individually for each room (S1, S2, S3), and outdoor air of the amount of air supplied individually set by the at least one damper (10, 11, 12, 13, 14) may be supplied or stopped. Air may be supplied to each room (S1, S2, and S3) through the at least one air supply passage (100, 110, 120, 130, and 140).

In addition, the control unit 40 may set the basic air supply amount for each room (S1, S2, S3) and the basic opening degree of the at least one air supply flow path (100, 110, 120, 130, 140) for forming the same.

Accordingly, the control unit 40 opens the at least one air supply passage (100, 110, 120, 130, and 140) that controls the at least one damper (10, 11, 12, 13, and 14) to each basic opening degree in each room (S1). The basic ventilation control can be used to control the supply of outdoor air equal to the basic air supply volume to each of S2 and S3).

The control unit 40 adjusts the opening degree of the at least one air supply passage (100, 110, 120, 130, and 140) as separate individual control is performed on the at least one damper (10, 11, 12, 13, and 14) in each room (S1). , S2, S3) is changed, and when the individual control is terminated, the at least one air supply flow path (100, 110, 120, 130, 140) returns to the open state at each basic opening degree, so that each room (S1, S2, S3) It can be controlled so that outdoor air is supplied as much as the basic air supply amount.

The basic opening degree may be set to the same opening degree in the at least one air supply passage (100, 110, 120, 130, 140), and may be set to a different opening degree depending on the purpose and area of each room.

For example, the kitchen (S2) is a space for cooking and eating, so it can be estimated that the pollution level is higher than that of other rooms, and the basic air supply amount to the kitchen (S2) is set to the basic air supply amount to the bedroom (S1) of the same area. By setting the air supply volume to be larger than the air supply volume and supplying a larger amount of outdoor air to the kitchen (S2), indoor air quality can be improved.

In addition, the control unit 40 controls whether or not to apply individual control to each room (S1, S2, S3), that is, each room damper that controls the opening degree of each room air supply passage connected to each room (S1, S2, S3) is individually controlled. Whether it is possible can be set, and ventilation operation can be performed by dividing rooms into rooms to which individual control is applied and rooms to which it is not applied.

The control unit 130 may set a standard pollution level that serves as a standard for distinguishing between the bad state and the good state.

Accordingly, when the pollution level of each room (S1, S2, S3) is higher than the standard pollution level, it is classified into the bad state, and when it is lower than the standard pollution level, it is classified into the good state.

The air quality rating standards of each country's Ministry of Environment or international environmental organizations such as WHO can be used as the standard polluted road.

The at least one air sensor (310, 320, 330) is provided to detect at least one of air pollutants that adversely affect human health, such as fine dust, carbon dioxide (CO2), and volatile organic compounds (TVOC), and the at least one air sensor (310, 320, 330) can be configured to measure air pollution levels for multiple types of pollutants, respectively.

The control unit 40 may operate the ventilation device based on the pollution level measured for a plurality of types of pollutants measured by the at least one air sensor 310, 320, and 330, and apply each pollutant to the ventilation system. The device can be operated repeatedly.

To this end, removal priorities for the plurality of types of contaminants may be set in the control unit 40, and a plurality of standard pollution levels corresponding to the plurality of types of contaminants may be set.

The control unit 40 operates the ventilation device by first applying the measured pollution level to the pollutants with the highest priority for removal, and then sequentially operates the ventilation device by sequentially applying the lower priority pollutants, thereby removing each pollutant. It is possible to create a comfortable environment that satisfies all requirements for cleanliness.

For example, the removal priority may be set in the order of fine dust, carbon dioxide (CO2), and volatile organic compounds (TVOC).

At this time, the control unit 40 classifies rooms with a fine dust pollution level higher than the fine dust standard pollution level among the plurality of rooms (S1, S2, and S3) as bad and operates the ventilation device, and thereafter, the carbon dioxide pollution level is reduced to a poor state. Rooms with higher than the standard pollution level can be classified as poor and the ventilation device can be operated. Then, rooms with a volatile organic compound pollution level higher than the volatile organic compound standard pollution level can be classified as bad and the ventilation device can be operated.

The control unit 40 operates the ventilation device by reapplying the pollutants with the highest removal priority after the operation of the ventilation device for the pollutants with the lowest priority for removal is completed, thereby operating the ventilation device. The contaminants can be applied sequentially and repeatedly.

In addition, the control unit 40 can determine the overall air pollution level of each room (S1, S2, and S3) by combining the measured air pollution levels for a plurality of types of pollutants, and operate the ventilation device based on this. It may be possible.

The at least one air sensor (310, 320, 330) may be an independent device separate from the ventilation device of the present invention, or may be a component included in the ventilation device of the present invention.

The at least one air sensor (310, 320, and 330) is provided to be easily movable, thereby improving the accuracy of air quality measurement for each room (S1, S2, and S3).

The at least one air sensor (310, 320, 330) is connected to the control unit 40 by wire or wirelessly and transmits the measured air pollution level information to the control unit 40.

At this time, as shown in the drawing, one air sensor 330 is mainly connected to the control unit 40, and the remaining air sensors 310 and 320 are connected to the control unit 40 through the main air sensor 330. It may be connected. At this time, the main air sensor 330 is a component included in the ventilation device, and the remaining air sensors 310 and 320 may be independent devices separate from the ventilation device.

Additionally, although not shown in the drawing, each air sensor 310, 320, and 330 may be connected to the control unit 40, respectively.

In addition, the at least one air sensor (310, 320, 330) can be connected to the control unit 40 through a plurality of methods, and if a problem occurs in connection by one method, it is connected through another method to transmit the measured pollution level. This can be done so that it is performed normally.

Methods for connecting the at least one air sensor (310, 320, 330) and the control unit 40 include wired connection and wireless connection, and at least one of a wireless network using Wi-Fi, a short-distance network such as Bluetooth, and a mobile communication network. may be included.

Additionally, the control unit 40 and the at least one air sensor 310, 320, and 330 may be interconnected through an application (not shown) installed on the terminal 400 connected through a network.

The application is configured so that the user registers the plurality of rooms (S1, S2, S3) and the at least one air sensor (310, 320, 330) to correspond to each other, and the air measured by the at least one air sensor (310, 320, 330) When the pollution level in the room is received by the terminal 400, it can serve as a medium to transmit it to the control unit 40 along with information on the corresponding rooms (S1, S2, and S3).

The user registers a newly additional air sensor in the application to measure the pollution level of each room (S1, S2, S3) and links it to the control unit 40, or deregisters the registered air sensor to control the control unit 40. ) can be canceled.

In addition, the at least one air sensor (310, 320, 330) is equipped with an alarm generator (not shown) that generates a set alarm, and the user can generate an alarm in the alarm generator through the application.

Accordingly, the user can determine the location of the at least one air sensor (310, 320, 330) through the application.

In addition, the correspondence relationship with each room (S1, S2, and S3) can be confirmed and modified by referring to the location identified as above.

Figure 3 is a flowchart showing a control method for controlling the ventilation device of the present invention.

Step S10 is a step in which the air pollution level of each room (S1, S2, and S3) is measured by at least one air sensor (310, 320, and 330) and transmitted to the control unit (40).

The pollution level measured by the at least one air sensor (310, 320, 330) may be for a plurality of pollutants.

The pollution level measured by the at least one air sensor 310, 320, and 330 is transmitted to the control unit 40 through an application installed on the terminal 400 and applied to control the operation of the ventilation device.

Measurement, transmission and application of the above pollution level can be done in real time.

In addition, prior to this step S10, a step of registering the at least one air sensor (310, 320, 330) in the application in a format corresponding to each room (S1, S2, S3) and linking it with the control unit 40 will be performed. You can.

In addition, the step of generating an alarm in any one of the at least one air sensor (310, 320, 330) through the application to determine the location of the relevant air sensor and confirming and correcting the correspondence with each room can be performed.

Step S20 is a step to determine and classify the status of each room (S1, S2, and S3) through the measured air pollution level.

The control unit 40 applies the pollution level of each room (S1, S2, and S3) measured from the at least one air sensor (310, 320, and 330), and classifies the room as poor if the applied pollution level is higher than the set standard pollution level. , if the applied pollution level is lower than the above standard pollution level, the room can be classified as good.

The control unit 40 performs step S30, which will be described later, when at least one of the plurality of rooms (S1, S2, and S3) is in a bad state, and when all of the plurality of rooms (S1, S2, and S3) are in a good state, the control unit 40 performs step S30. In this case, step S40 described later is performed.

The pollution level applied as above may be a comprehensive air pollution level determined by combining the pollution levels caused by a plurality of pollutants measured by the at least one air sensor 310, 320, and 330.

Additionally, the pollution level applied as above may be the pollution level for any one of the plurality of pollutants, and may be applied sequentially according to the removal priority set in the control unit 40.

Step S30 is a step in which the room is ventilated by operating the ventilation device according to the pollution level of the room classified as poor.

This step S30 is performed as one of steps S31 to S33 below, depending on whether the amount of air supplied to each room is individually adjusted by the at least one damper 10, 11, 12, 13, or 14.

At this time, whether or not the air supply amount is individually controlled may be a condition determined when installing the ventilation device of the present invention, and when installing the ventilation device, any one of steps S31 to S33 below can be set to be performed fixedly. .

In another embodiment, when the ventilation device is first operated, whether or not the air supply amount to each room is individually adjusted is determined in step S30, and any one of the following steps S31 to S33 is set to be performed fixedly, and then During operation, preset steps among steps S31 to S33 below may be performed without determining whether or not to individually adjust the air supply amount.

In step S31, when the at least one damper (10, 11, 12, 13, and 14) is controlled collectively and the air supply amount to each room is adjusted collectively, the plurality of rooms (S1, S2, and S3) This is a step taken to provide uniform ventilation.

The control unit 40 applies the contamination level of the room with the highest contamination level among the rooms classified as poor in step S20 and operates the at least one damper 10, 11, 12, 13, and 14 in batches. By controlling, the total amount of outdoor air flowing into the room can be adjusted.

The total amount of air supply can be adjusted in proportion to the applied pollution level.

That is, according to this step S31, when at least one of the plurality of rooms (S1, S2, S3) is in the bad state, the indoor ventilation rate is increased by increasing the total amount of air supplied according to the degree of contamination of the room, thereby quickly reducing the bad state. It can solve the problem and create a comfortable indoor environment.

In step S32, when the at least one damper (10, 11, 12, 13, and 14) is individually controlled and the air supply amount to each room is individually adjusted, each room (S1, S2, and S3) is individually controlled, This step provides selective ventilation.

The control unit 40 closes the air supply passage connected to the room classified as good, thereby blocking the air supply, and opens the air supply passage connected to the room classified as bad, to supply outdoor air to each room (S1, S2, and S3). can be introduced selectively.

At this time, the control unit 40 individually controls the operation of the at least one damper 10, 11, 12, 13, and 14, so that the air flows into each room according to the degree of pollution in each room classified as poor. The amount of outdoor air supplied can be individually adjusted.

For example, when the bedroom (S1) and the kitchen (S2) are in a bad state and the living room (S3) is in a good state, the control unit 40 blocks the air supply to the living room (S3) and simultaneously operates the bedroom (S1). The air can be selectively supplied to the bedroom (S1) and the kitchen (S2). In this case, the amount of outdoor air supplied to the bedroom (S1) and the kitchen (S2) can be formed in proportion to the degree of pollution in each room.

In addition, the control unit 40 individually controls the operation of the at least one damper 10, 11, 12, 13, and 14 to control the operation of each room according to the basic air supply amount of each room classified as poor. The amount of outdoor air flowing into can be individually adjusted.

At this time, the excess air supply generated when the air supply to the room classified as good is cut off and additionally distributed to the room classified as bad, and the additional air supply distributed to each room classified as bad is It can be formed in proportion to the basic air supply amount of the room.

For example, the bedroom (S1) and the kitchen (S2) are in a bad state, the living room (S3) is in a good state, the total air supply amount is 100, and the bedroom (S1), the kitchen (S2), and the living room When the basic air supply amount to (S3) is set to 20, 30, and 50, respectively, the living room (3) is blocked and the surplus air supply amount of 50 generated is supplied to the bedroom (S1) and the kitchen (S2) at 20:30. Additional distribution may be made at the rate of

Accordingly, the air supply quantity to the bedroom (S1) is formed as 40, which is the basic air supply quantity of 20 plus the additional air supply quantity of 20, and the air supply quantity to the kitchen (S2) is the basic air supply quantity of 30 plus the additional air supply quantity of 30. It is formed at 60, and the total air supply amount is maintained at 100.

That is, according to this step S32, when at least one room among the plurality of rooms (S1, S2, S3) is in the bad state, the air supply to the room classified in the good state is blocked and at the same time, the air supply to the room classified in the bad state is blocked. By selectively supplying outdoor air, bad conditions can be quickly eliminated and a comfortable indoor environment can be created.

In addition, by additionally distributing the excess air supply generated when the rooms classified into the good state are blocked to the rooms of the bad state, the bad state can be quickly eliminated and a pleasant indoor environment can be created.

In step S33, only some of the at least one dampers (10, 11, 12, 13, and 14) are individually controlled, excluding rooms to which individual control is not applied among the plurality of rooms (S1, S2, and S3). This is the step to provide individual and selective ventilation only for the rooms to which it is applied.

Whether to apply individual control to each room (S2, S2, S3) can be set in the control unit 40.

According to this step S33, the control unit 40 controls the rooms to which individual control is applied, excluding the rooms to which individual control is not applied among the at least one room (S1, S2, S3), as described in step S32. Perform the same control process.

For example, individual control is applied to the bedroom (S1), the kitchen (2), and the living room (3), and a bathroom (not shown) space to which individual control is not applied is further provided, and an air supply flow path is provided in the bathroom. If outdoor air does not flow in because it is not connected or blocked, the bedroom (S1), the kitchen (2), and the living room (3) as described in step S32 without considering the supply air to the bathroom. Carry out the control process.

When all are in a good state, step S40 described later is performed.

In addition, when the pollution level for any one of the plurality of types of pollutants measured by the at least one air sensor (310, 320, 330) is applied in step S20, the pollution level of the plurality of rooms (S1, S2, and S3) is increased. When all are in a good state, steps S20 and below can be repeated by applying contamination levels for the previously applied contaminants and other contaminants.

Accordingly, it is possible to form a comfortable environment that satisfies the cleanliness level for multiple types of contaminants.

At this time, as described above, the plurality of types of contaminants may be sequentially applied according to the removal priority for each repeated performance.

In addition, when the plurality of rooms (S1, S2, S3) are all in a good state with respect to the plurality of types of contaminants, step S40, which will be described later, is performed.

Step S40 is a step in which the plurality of rooms (S1, S2, and S3) are all determined to be in a good state and the ventilation device is operated in the basic mode.

According to this step S40, the control unit 40 controls the at least one damper 10, 11, 12, and 13 to supply outdoor air equal to the standard air supply amount to each room (S1, S2, and S3). can do.

This step S40 is performed until one of the plurality of rooms (S1, S2, and S3) is classified as poor according to the degree of contamination transmitted from the at least one air sensor (310, 320, and 330), and the plurality of rooms (S1) If any one of the pollution levels in S2 and S3) becomes bad, the process can return to step S30.

As described above, according to the ventilation device and its control method according to the present invention, the comfort of indoor life can be improved by managing to improve indoor air quality by adjusting the amount of air supplied according to the degree of pollution in each room (S1, S2, S3). You can.

In addition, by repeatedly performing ventilation based on the degree of contamination of a plurality of contaminants, a comfortable environment that satisfies the degree of cleanliness of the plurality of contaminants can be created.

In addition, ventilation can be selectively performed only for rooms in a bad state, excluding rooms in a good state, thereby providing more rapid ventilation and increasing the comfort of indoor life.

In addition, by distributing the amount of air supplied in proportion to the level of pollution in each room, more efficient ventilation can be provided and the comfort of indoor life can be improved.

In addition, the air sensor in each room (S1, S2, S3) and the control unit 40 are connected through the terminal application, making settings such as adding and deleting air sensors easy.

In addition, the above application generates an alarm on the air sensor to check and adjust the location where the air sensor is installed, so that the air quality in each room (S1, S2, S3) can be more accurately identified and the air quality in each room (S1, S2, S3) is The ventilation device can be controlled in response to the condition.
