Referring to the drawings, the ventilation device according to the present invention includes a device main body 100 and a control unit (C).

Here, the device main body 100 includes a first exhaust chamber 110, a second exhaust chamber 120, a first air supply chamber 130, a second air supply chamber 140, and a total heat exchanger 150. It can be provided.

The first exhaust chamber 110 has an exhaust inlet 110a through which indoor air flows, that is, return air (RA) flows in.

This exhaust inlet 110a is connected to the exhaust duct 10, which has a structure extending into the living room and a plurality of rooms.

In addition, the exhaust duct 10 has a living room exhaust inlet 10a formed at the end of the living room side through which the indoor air from the living room flows in to exhaust the indoor air from the living room side, and a living room exhaust inlet 10a through which the indoor air from the living room flows in is formed at the end of the room side to exhaust the indoor air from the room side. A room exhaust inlet (10b) through which indoor air flows into the room is formed.

A flow control member 11 may be installed in each of the living room exhaust inlet (10a) and the room exhaust inlet (10b), and the living room exhaust inlet (10a) and the room exhaust inlet may be connected depending on the degree of opening and closing of the flow control member (11). The amount of indoor air flowing into (10b) can be adjusted or the inflow itself can be blocked.

In addition, the second exhaust chamber 120 has a structure that communicates with the first exhaust chamber 110, and is specifically connected through a total heat exchanger 150.

This second exhaust chamber 120 has an exhaust outlet 120a through which indoor air passing through the first exhaust chamber 110 is discharged to the outdoors, that is, exhaust air (EA) flows out to the outside.

In addition, the second exhaust chamber 120 is equipped with an exhaust fan 121 inside, and by the operation of the exhaust fan 121, indoor air is drawn in through the exhaust duct 10 and the first exhaust chamber 110. do.

In addition, the first air supply chamber 130 has an air supply inlet 130a through which outdoor air (OA) flows in.

In addition, the second air supply chamber 140 has a structure in communication with the first air supply chamber 130, and is specifically connected through a total heat exchanger 150.

This second air supply chamber 140 has a supply air outlet 140a through which outdoor air via the first air supply chamber 130 is supplied indoors, that is, supply air (SA, Supply Air) flows out.

This air supply outlet (140a) is connected to the air supply duct 20, which has a structure extending into the living room and a plurality of rooms.

In addition, the air supply duct 20 has a living room air supply outlet 20a formed at the end of the living room side through which outdoor air flows out in order to supply outdoor air into the living room, and a living room air outlet 20a through which outdoor air flows out is formed on the living room side to supply outdoor air into the room. An air discharge outlet (20b) through which outdoor air flows out is formed at the end.

A flow control member 11 may be installed in each of the living room air supply outlet (20a) and the air supply outlet (20b), and depending on the degree of opening and closing of the flow control member 11, the living room air supply outlet (20a) and the air supply outlet (20b) may be installed. The outflow amount of outdoor air flowing out of the outlet 20b can be adjusted or the outflow itself can be blocked.

In addition, the second air supply chamber 140 is equipped with an air supply fan 141 inside, and by the operation of the air supply fan 141, external outdoor air is drawn in through the first air supply chamber 130.

Meanwhile, the control unit (C) is linked to the device main body 100, and as shown in the drawing, it can have a structure directly connected to the device main body 100, and although not shown in the drawing, it can be used like an intermediate control device. It can have a structure that is spaced apart from the device main body, and can furthermore have a structure that is placed in the living room and each room like a room controller.

That is, of course, the control unit (C) can have any conventional shape and arrangement as long as it is electrically connected to the device body 100 in a wired or wireless manner.

As shown in FIG. 2, the control unit C can be selectively operated in one of the ventilation operation, cleaning operation, and cooking operation processes.

At this time, the ventilation operation is a process of ventilating the room by supplying outdoor air into the room while exhausting the indoor air, and the cleaning operation is a process of circulating and filtering the indoor air through the device body 100 without exhausting the indoor air to the outside to purify the indoor air. It is a process that purifies the food, and the cooking operation is a process that provides air supply so that it can be smoothly exhausted through the hood when cooking in the kitchen. The present invention provides a cooking operation process in which the user does not feel the cold draft of supplied air and the high temperature and humidity during the cooking operation.

Specifically, when the control unit (C) receives an operation signal from the hood (1) provided in the kitchen, it controls the exhaust blocking mode, suction mode, and air supply mode to operate in conjunction with each other.

First, the control unit (C) is electrically connected to the operating motor of the hood (1), and receives an operating signal when the operating motor of the hood (1) is activated.

In addition, the exhaust blocking mode is a mode in which the control unit (C) closes the exhaust outlet (120a) of the second exhaust chamber 120, and the control unit (C) closes the exhaust outlet door (not shown) mounted on the exhaust outlet (120a). ) is achieved by closed control.

In this exhaust blocking mode, even if the exhaust fan 121 of the second exhaust chamber 120 is operated, indoor air is blocked from being discharged to the outside through the second exhaust chamber 120.

For reference, exhaust blocking in the exhaust blocking mode means blocking the final discharge of indoor air to the outside, and exhausting indoor air through the exhaust duct 10, which will be described later, involves sucking indoor air into the exhaust duct 10. This means that it only flows into the device body 100 and is not discharged to the outside.

In addition, the suction mode is a mode in which the control unit (C) sucks indoor air and external outdoor air into the device main body, and the control unit (C) operates and controls the exhaust fan 121 of the second exhaust chamber 120. 2 This is achieved by operating and controlling the air supply fan 141 in the air supply chamber 140.

Specifically, the control unit (C) controls a flow rate control device mounted on the living room exhaust inlet (10a) of the exhaust duct (10) provided in the living room so that indoor air flows into the exhaust duct (10) only in a plurality of rooms in the suction mode. The member 11 can be controlled closed.

For reference, in the present invention, controlling various devices or devices through the control unit (C) includes electrically connecting the various devices or devices to the control unit (C) or communicating wirelessly with the corresponding device, mechanism, or member, Furthermore, signals may be transmitted through other relay devices.

In this way, the indoor air used for supply air is only the indoor air exhausted from multiple rooms, excluding the living room, which is located relatively far away from the kitchen while maintaining the warm indoor air in the living room adjacent to the kitchen. By exhausting and recycling only the indoor air in the room, the air supplied to the kitchen can be maintained at the highest temperature possible.

Furthermore, in the air supply mode described later, the indoor air used for supply air is mixed with outdoor air within the device main body 100 and then supplied indoors, thereby increasing the temperature of the outdoor air coming from outside, thereby reducing the temperature of the air supplied to the kitchen. The temperature can be raised even further.

Of course, contrary to the above, it is also possible to use only the indoor air exhausted from the living room, and it is also possible to select and use all or part of the indoor air from the living room and a plurality of rooms.

The air supply mode is a mode in which indoor air and external outdoor air are mixed within the device body 100 and then supplied indoors, and the control unit C controls the outdoor air introduced into the first air supply chamber 130 as described above. This is done by adding indoor air to outdoor air and adding indoor air to it.

As described above, by mixing outdoor air and indoor air in the device main body 100 in the air supply mode, for example, the temperature of outdoor air taken in in winter is raised or the temperature and humidity of hot and humid outdoor air taken in in summer are increased. By lowering the temperature, users inside the room may not feel cold and high temperature and humidity from the supplied air.

In addition, the control unit (C) can mix indoor air with outdoor air within the device body 100 after passing through the total heat exchanger 150 in the air supply mode. In this way, before the indoor air and outdoor air are mixed, heat is exchanged in the total heat exchanger 150 and heat is applied to the outdoor air, so that the outdoor air sucked into the device main body 100 has a relatively higher temperature than the outside. It is possible to prevent condensation from occurring within the device body 100 by preventing the dew point from reaching the dew point within the device body 100.

Furthermore, after receiving the operation signal of the hood 1, the control unit C can control the exhaust blocking mode, suction mode, and air supply mode to last for a certain period of time and then stop.

In this way, the control unit (C) may be configured with a timer control function. As an example, after the user operates the hood (1) during cooking, the user forgets to stop the operation of the hood (1) even after cooking is completed. ), if the operation is maintained for too long, this is to prevent it from continuously operating in the cooking operation process and to allow the operation to be switched to the ventilation or cleaning operation process.

Here, various embodiments related to the air supply mode will be examined with reference to FIGS. 2 to 8.

Referring to FIGS. 3 and 4, in one embodiment, the control unit (C) adopts a control configuration that supplies exhausted indoor air to the air supply duct 20 through the first bypass chamber (1B).

Specifically, the device main body 100 may further include a first bypass chamber 1B that communicates the second exhaust chamber 120 and the first air supply chamber 130, and the first bypass chamber ( 1B) may be provided with a first bypass door (1D). For reference, the first bypass chamber 1B and the second bypass chamber 2B, which will be described later, may be formed independently as shown in the drawing, but are not limited to this and can be combined with each other to form a lower part of the device body 100. It may be a bypass space formed as a floor space.

Here, the first bypass door (1D) communicates with the second exhaust chamber 120 and the first air supply chamber 130 when opened, and communicates with the second exhaust chamber 120 and the first air supply chamber 130 when closed. It does not pass through, and the specific structure is not limited by the present invention, and of course, any conventional opening/closing door structure can be used.

As shown, this first bypass door (1D) is a connection part between the first bypass chamber (1B) and the second exhaust chamber 120, and the first bypass chamber (1B) and the first air supply chamber 130. It can be mounted on each of the connection parts, and further, although not shown in the drawing, if configured to open and close the communication space between the second exhaust chamber 120 and the first air supply chamber 130, the first bypass chamber (1B) ) Of course, it can be installed anywhere inside.

Furthermore, a bypass fan (f) may be installed in the first bypass chamber (1B) to flow indoor air from the second exhaust chamber (120) to the first air supply chamber (130). This bypass fan may be installed in the first bypass chamber (1B). (f) serves to facilitate the flow of indoor air from the second exhaust chamber 120 to the first air supply chamber 130. In addition, although not shown in the drawings, a bypass fan may be installed in the second bypass chamber 2B in FIGS. 5 and 6, and a bypass fan may be installed in the third bypass chamber 3B in FIGS. 7 and 8. Of course, a fan can be installed.

And, in the air supply mode, the control unit (C) introduces indoor air from the first exhaust chamber 110 into the first air supply chamber 130 through the second exhaust chamber 120 and the first bypass chamber 1B. To do this, the first bypass door 1D can be opened and the exhaust fan 121 of the second exhaust chamber 120 can be operated and controlled. At this time, since the exhaust outlet 120a of the second exhaust chamber 120 is closed in the exhaust blocking mode, it goes without saying that air is not discharged to the outside through the exhaust outlet 120a of the second exhaust chamber 120.

Accordingly, the control unit (C) can supply the indoor air introduced into the first air supply chamber 130 into the room by sequentially passing the first air supply chamber 130 and the second air supply chamber 140 together with the outdoor air. there is.

Referring to FIGS. 5 and 6 as another embodiment, the control unit (C) adopts a control configuration that supplies exhausted indoor air to the air supply duct 20 through the second bypass chamber (2B).

Here, when the second bypass door (2D) is opened, it passes through the exhaust outlet (120a) and the air supply inlet (130a), and when closed, it does not pass through the exhaust outlet (120a) and the air supply inlet (130a), and has a specific structure. Of course, the present invention is not limited and any conventional opening/closing door structure can be used.

As shown, the second bypass door (2D) is formed at the connection portion between the second bypass chamber (2B) and the exhaust outlet (120a) and the connection portion between the second bypass chamber (2B) and the air supply inlet (130a), respectively. It can be mounted on, and further, although not shown in the drawing, it can be mounted anywhere inside the second bypass chamber (2B) as long as it is configured to open and close the communication space between the exhaust outlet (120a) and the air supply inlet (130a). Of course.

And, in the air supply mode, the control unit (C) introduces indoor air from the first exhaust chamber 110 into the first air supply chamber 130 through the second exhaust chamber 120 and the second bypass chamber 2B. To do this, the second bypass door 2D can be opened and the exhaust fan 121 of the second exhaust chamber 120 can be operated and controlled.

Accordingly, the control unit (C) sequentially passes the indoor air introduced into the first air supply chamber 130 through the first air supply chamber 130 and the second air supply chamber 140 together with the outdoor air to form the air supply duct 20. ) can be supplied.

At this time, since the exhaust outlet 120a of the second exhaust chamber 120 is closed in the exhaust blocking mode, it goes without saying that air is not discharged to the outside through the exhaust outlet 120a of the second exhaust chamber 120.

Meanwhile, in FIGS. 3 to 6, the control unit (C) controls the indoor air and outdoor air to exchange heat in the total heat exchanger 150, but in another embodiment of FIGS. 7 and 8, the control unit (C) controls the indoor air and outdoor air to exchange heat. The configuration is such that the indoor air is controlled to move directly to the first air supply chamber 130 without intersecting with each other in the total heat exchanger 150 to exchange heat.

Of course, in the embodiment shown in FIGS. 7 and 8, as in FIGS. 3 to 6, the control unit C is provided in the living room to allow indoor air to flow into the exhaust duct 10 only from a plurality of rooms in the air supply mode. It has a configuration that closes and controls the flow rate control member (11) mounted on the living room exhaust inlet (10a) of the exhaust duct (10).

And, in the embodiments of FIGS. 7 and 8, the control unit (C) has a control configuration that supplies the exhausted indoor air to the air supply duct 20 through the third bypass chamber (3B).

Specifically, the device main body 100 may further include a third bypass chamber 3B communicating with the first exhaust chamber 110 and the first air supply chamber 130, and the third bypass chamber ( 3B) may be provided with a third bypass door (3D).

Here, the third bypass door (3D) communicates with the first exhaust chamber 110 and the first air supply chamber 130 when opened, and communicates with the first exhaust chamber 110 and the first air supply chamber 130 when closed. It does not pass through, and the specific structure is not limited by the present invention, and of course, any conventional opening/closing door structure can be used.

As shown, this third bypass door (3D) is a connection portion between the third bypass chamber (3B) and the first exhaust chamber (110), and the third bypass chamber (3B) and the first exhaust chamber (110). It can be mounted on each connection part, and further, although not shown in the drawing, if configured to open and close the communication space between the first exhaust chamber 110 and the first air supply chamber 130, the third bypass chamber (3B) ) Of course, it can be installed anywhere inside.

And, in the air supply mode, the control unit (C) opens the third bypass door to allow indoor air in the first exhaust chamber (110) to flow into the first air supply chamber (130) through the third bypass chamber (3B). (3D) can be controlled open. At this time, the control unit (C) operates at a portion in the first exhaust chamber 110 that communicates with the second exhaust chamber 120 to prevent the indoor air in the first exhaust chamber 110 from moving toward the second exhaust chamber 120. Of course, the exhaust room connection door (not shown) installed in is controlled to close.

Accordingly, the control unit (C) sequentially passes the indoor air introduced into the first air supply chamber 130 through the first air supply chamber 130 and the second air supply chamber 140 together with the outdoor air to form the air supply duct 20. ) can be supplied.

Meanwhile, indoor air and outdoor air are mixed in the first air supply chamber 130, and the air mixed in this way and flowing out from the air supply outlet 140a of the second air supply chamber 140 is shown in FIGS. 3, 5, and 5. As shown in FIG. 7, the air is supplied indoors through the air supply duct 20 and then guided to the kitchen hood 1 by the air supply blower 30, or as shown in FIGS. 4, 6, and 8. Air can be supplied directly to the kitchen as well as to multiple rooms and living rooms.

Specifically, as shown in FIGS. 3, 5, and 7 as an example, the air supply outlet 140a may be connected to the air supply duct 20, whereby the air flowing out from the air supply outlet 140a is connected to the air supply duct 20. Air can be supplied to the indoor living room and a plurality of rooms through the duct 20.

Here, the control unit (C) can control the blowing mode to operate in conjunction with guiding the air supplied to the living room and a plurality of rooms to the hood (1) through the air supply blower (30) installed on the ceiling.

Allow it to be sent to your side.

For reference, comparing the air flow ratio as an example, under the condition that 200% of indoor air is discharged through the hood (1), 200% of external outdoor air is sucked in from the device body (100) as a countermeasure, and then the supply air is Through the duct (20), 30 air supply is supplied to each of room 1 and room 2, 40 air supply is supplied to room 3, and 50 air supply is supplied to each living room 1 and living room 2.

In addition, the device body 100 inhales 30 indoor air from each of rooms 1 and 2 and 40 from room 3 through the exhaust duct 10, for a total of 100, and then inhales 100 more indoor air through the exhaust duct 10. Through this, an additional 15 air supply is supplied to room 1, room 2, and room 3, and an additional 15 air supply is supplied to living room 1 and living room 2.

As a result, the final supplied air flow rate is 45 in room 1 and room 2, 60 in room 3, and 75 in living room 1 and living room 2.

As another example, as shown in FIGS. 4, 6, and 8, the air supply outlet 140a is connected to the air supply duct 20, and the air supply duct 20 flows through the kitchen before reaching a plurality of rooms and the living room. It can be connected to the kitchen duct (40).

At this time, the control unit (C) controls the flow rate installed at the kitchen air outlet (40a) of the kitchen duct (40) provided in the kitchen to supply the heat-exchanged indoor air to the kitchen along with the plurality of rooms and the living room in the air supply mode. The adjusting member 41 can be controlled to open.

For reference, comparing the air flow ratio as an example, under the condition that 200% of indoor air is discharged through the hood (1), 200% of external outdoor air is sucked in from the device body (100) as a countermeasure, and then the supply air is Through the duct (20), 30 air supply is supplied to each of room 1 and room 2, 40 air supply is supplied to room 3, and 50 air supply is supplied to each living room 1 and living room 2.

In addition, the device body 100 inhales 30% of indoor air from rooms 1 and 2, and 40% from room 3 through the exhaust duct 10, for a total of 100, and then inhales 100% of the indoor air through the exhaust duct 10 into the kitchen. Sudden 100.

As such, the present invention is configured to supply air to the living room and a plurality of rooms through the air supply duct 20 in the air supply mode and guide the air supplied to the kitchen through the air supply blower 30, or to the kitchen through the kitchen air outlet 40a. By being configured to supply air directly to the kitchen, the exhaust action through the hood (1) can be smoothly performed when cooking in the kitchen, and at the same time, since the air supplied is indoor air, the user is exposed to cold, hot and humid air from the supplied air. You don't feel the condition.

Meanwhile, as shown in FIGS. 3 to 8, the device main body 100 may have a heater (H) installed at the rear end of the exhaust inlet (110a), and this heater (H) connects the exhaust duct (10). It plays the role of heating the indoor air introduced through it.

As the heater H heats the indoor air introduced through the exhaust duct 10, the temperature of the outdoor air is further increased when heat is exchanged between the indoor air and the outdoor air in the total heat exchanger 150, thereby increasing the temperature, especially in winter. It is possible to prevent condensation from occurring inside the device main body 100 due to low outdoor air.

As an example, let's look at temperature changes in indoor air and outdoor air caused by a heater installed in a ventilation device as shown in FIG. 9.

Here, as an experimental condition, the air ratio between outdoor air and indoor air flowing into the device body is 2:1, the temperature of the outside outdoor air is -15℃ as indicated at point OA in the drawing, and the temperature of the indoor air is as shown in the drawing. It is 20℃ as indicated at point RA.

First, when the heater is not used, when the outdoor air and indoor air flowing into the device body are mixed, the temperature of the mixed air becomes -3.2℃ as shown at point OA-2 in the drawing. In this case, the dew point is reached. Accordingly, condensation occurs inside the device body.

On the other hand, when the heater is used, the indoor air flowing into the device body is heated by the heater to reach 35°C as indicated at the RA (heater) point in the drawing, so the heated indoor air and the indoor air flowing into the device body are heated. When outdoor air is mixed, the temperature of the mixed air becomes 1.8°C as indicated at the OA (heater) point in the drawing, and the dew point is not reached, so condensation does not occur inside the device body.

As a result, the ventilation device according to the present invention adopts a control configuration in which the control unit (C) operates in conjunction with the exhaust blocking mode, suction mode, and air supply mode after receiving the operation signal of the hood (1), so that it can be used in outdoor areas where the temperature is low. By raising the temperature of the air or adjusting hot and humid outdoor air to an appropriate temperature and lowering the humidity, it is possible to prevent users indoors from feeling cold and hot and humid conditions, thereby preventing discomfort to users.

As described above, although the present invention has been described with limited examples and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following will be understood by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalence of the patent claims to be described.
