Unexplained reference numeral 20 denotes the exhaust device 20 provided in the toilet.

2 is a plan view of the exhaust device 10 and the air supply ports 130 and 140 viewed from above.

A gas or electric range 20 is installed under the exhaust device 10 . If an imaginary straight line extending from the front surface H1 and both sides H2 and H3 of the exhaust device 10 is drawn, two areas A1 and A2 indicated by hatched lines can be set.

A direction in which a third air inlet 150 to be described later is located on the front surface H1 of the exhaust device 10 is referred to as a front, and the opposite direction is referred to as a rear.

Among the two areas A1 and A2, an area surrounded by a straight line extending to the left from the front surface H1 and a straight line extending downward from the first side surface H2 is called a first left and right area A1, A region surrounded by a straight line extending to the right from H1 and a straight line extending downward from the second side surface H3 is referred to as a second left and right region A2.

The first left and right areas A1 and the second left and right areas A2 are in front of the front surface H1 of the exhaust device 10 , and are respectively formed outside both side surfaces H2 and H3 of the exhaust device 10 . to be.

A first air inlet 130 is provided in the first left and right area A1, and a second air inlet 140 is provided in the second left and right area A2.

When the first air inlet 130 and the second air inlet 140 are provided at such a position to supply air during cooking, the contaminated air generated during cooking is efficiently discharged to the outside through the exhaust device 10 . It can be exhausted, and it is possible to prevent the spread of polluted air into the indoor space.

In this case, the first air inlet 130 may be provided such that the air is supplied in a direction toward the front H1 and the first side H2 of the exhaust device 10 at the same time.

In addition, the second air inlet 140 is provided such that the direction in which air is supplied faces the front H1 of the exhaust device 10 and the second side H3 opposite to the first side H2 at the same time. can be

When food is cooked in the range 20 , the contaminated air flows upward, and a portion of the flowing contaminated air is discharged to the outside through the exhaust device 10 , but the remaining part is It can flow toward the ceiling of the kitchen through the front surface (H1) and both sides (H2, H3) and diffuse into the indoor space.

As described above, when the air supplied through the first air inlet 130 and the second air inlet 140 is directed toward the front surface (H1) and the side surfaces (H2, H3) of the exhaust device 10, the range 20 It is possible to prevent the polluted air flowing upward from above from flowing toward the ceiling on the front H1 and both sides H2 and H3 that are outside of the exhaust device 10 . Accordingly, it is possible to prevent the polluted air from diffusing into the indoor space.

In addition, the cook cooks standing in front of the front surface (H1) of the range (20), the first air inlet 130 or / and the second air inlet (140) both sides (H2, H2, When located in the third area A3 formed between the planes extending forward in H3), the air supplied from the first air inlet 130 or the second air inlet 140 affects the cook and cooks may cause discomfort. Therefore, by providing the first air inlet 130 and the second air inlet 140 in the first left and right area (A1) or the second left and right area (A2) out of the third area (A3), the air supplied to the cook is influence can be prevented.

In this case, the fact that the first air inlet 130 is located in the first left and right area A1 means that at least a portion of the passage 130a through which air flows inside the first air inlet 130 is located in the first left and right area A1. ) can be defined as being located in It can be defined in the same meaning that the second air inlet 140 is located in the second left and right area (A2). That is, even if the center of the first air inlet 130 or / and the second air inlet 140 is located in the third area A3, if the length of the air inlets 130 and 140 is sufficiently long in the horizontal direction, the supplied air One of the side surfaces H2 and H3 of the exhaust device 10 and the front surface H1 may be simultaneously supplied.

Of the air supplied from the first air inlet 130, the air toward the front surface (H1) and the air toward the front surface (H1) of the air supplied from the second air inlet 140 is the front surface (H1) of the range 20 ), the air supply direction of the first air supply port 130 and the second air supply port 140 can be set so that a predetermined section overlaps in the central portion to form an overlapping section (O). When the overlapping section O is formed in this way, it is possible to effectively prevent the contaminated air from leaking in the ceiling direction riding on the front surface H1 of the exhaust device 10 .

A linear distance between the first air inlet 130 and the exhaust device 10 and the linear distance between the second air inlet 140 and the exhaust device 10 may be the same. The same linear distance means that the first air inlet 130 and the second air inlet 140 are provided in a position symmetrical to the left and right with respect to the center line C in the front and rear direction of the exhaust device 10 case and the case where the position is not symmetrical in the left and right direction with respect to the center line (C) is included.

The second distance D2 between them is the same.

In this case, when the first air inlet 130 and the second air inlet 140 have a different distance from the center line (C), the linear distance is different. Moreover, it becomes asymmetric with respect to the center line (C).

The longer the linear distance between the exhaust device 10 from the first air inlet 130 and the second air inlet 140 is, the greater the air resistance until it is discharged from the air inlets 130 and 140 and reaches the exhaust device 10 . The closer the straight line, the less air resistance.

Therefore, when the linear distance between the first air inlet 130 and the exhaust device 10 and the linear distance between the second air inlet 140 and the exhaust device 10 are different, from the exhaust device 10 It can be set so that the air supply amount of the air supply port having a long linear distance of is greater than the air supply amount of the air supply port having a linear distance from the exhaust device 10 . Due to this, the air supplied from the first air inlet 130 and the second air inlet 140 can reach the exhaust device 10 uniformly.

As described above, when air is supplied from the air inlets 130 and 140 toward the exhaust device 10 , even when the exhaust device 10 is operated at a low intensity, pollutants are smoothly exhausted to the outdoors through the exhaust device 10 to remove indoor pollutants. The concentration reduction effect can be improved. In addition, when the exhaust device 10 is operated at a low intensity, energy required for the operation of the exhaust device 10 can be reduced.

In addition, the air supplied from the third air inlet 150 may be configured not to face the exhaust device 10, but to face other directions such as the floor or wall, and directed in all directions along the entire perimeter of the third air inlet 150 It can also be configured to

In the above, only the first front/rear area (Z1) and the second front/rear area (Z2) were divided, but in front of the third air inlet 150, a fourth air inlet (not shown) and a fifth air inlet (not shown) Further provided, the fourth air inlet is provided in a third front and rear area (not shown) formed in front of the second front and rear area (Z2), and the fifth air inlet is provided in front of a fourth front and rear area formed in front of the third front and rear area A plurality of front and rear areas and a plurality of air inlets may be further provided in addition to the first and second front and rear areas Z1 and Z2, such as being provided in an area (not shown).

In addition, the first air inlet 130 and / or the second air inlet 140 may be located between the virtual straight lines extending from both sides (H2, H3), respectively. In this case, the air supplied from the first air inlet 130 or the second air inlet 140 is not directly supplied toward the first side (H2) or the second side (H3), but rather the first side (H2) ) is supplied toward the space on the left side or the space on the right side of the second side (H3).

A flow velocity interface 13 may be formed at a lower portion of the suction unit 12 . The area surrounded by the suction part 12 and the flow velocity interface 13 represents an area in which contaminants can be smoothly exhausted by the set air volume of the exhaust blower 11 .

When the air volume of the exhaust blower 11 is determined, the distance L from the flow velocity interface 13 to the air supply ports 130 and 140 may be determined.

If the distance between the supply ports 130 and 140 and the exhaust device 10 is too close, the flow rate of the supplied air becomes greater than the flow velocity inside the flow velocity interface 13, so the flow field inside the flow velocity interface 13 There may be a problem in that the destroyed and contaminated material cannot be smoothly sucked in the suction unit 12 .

Since it is desirable to match the flow velocity when the air supplied from the inlet ports 130 and 140 reaches the flow velocity interface 13 and the flow velocity inside the flow velocity interface 13 due to being sucked in by the exhaust blower 11, it is preferable. , It is possible to determine the distance (L) to the air inlet (130,140) in consideration of this point.

The blocking plate 16 may be provided in a structure movable in the vertical direction on at least one side of the exhaust device 10 . When the blocking plate 16 descends to block at least a portion of the lower space of the exhaust device 10 , it is possible to prevent contaminated air from leaking out of the exhaust device 10 and spreading into the indoor space.

When the blocking plate 16 is provided on both sides H2 and H3 of the exhaust device 10, it may cause inconvenience to the cook. Therefore, it is preferable to be provided only on one side of the exhaust device (10).

In addition, when the air supply ports 130 and 140 are provided on only one side of the first left and right areas A1 or the second left and right areas A2 outside both sides H2 and H3 of the exhaust device 10 , the exhaust device The blocking plate 16 may be provided on the opposite side to the position where the air supply ports 130 and 140 are provided among both sides H2 and H3 of (10). With this configuration, the blocking plate 16 prevents the air polluted by the air supplied from the air supply ports 130 and 140 from being pushed out in the lower space of the exhaust device 10 in the opposite direction to the direction in which the air supply ports 130 and 140 are located. can be prevented

A method for controlling an air supply device according to the present invention will be described.

When the cook cooks in the kitchen, the exhaust device 10 is operated manually or automatically to exhaust the polluted air to the outside.

Depending on the operation of the exhaust device 10, the air supply device 100 is operated manually or automatically. That is, when an air supply signal for manual or automatic operation is received by the air supply signal receiving unit 111 , the air supply blower 120 is operated.

In this case, the air supply blower 120 may be operated at a preset rotation speed to supply the amount of air required by the first to third air supply mechanisms 130, 140, and 150, and the first to third air supply mechanisms 130, 140, and 150 ) may vary the rotational speed of the air supply blower 120 in the air supply control unit 112 to adjust the air supply amount. In addition, the opening degree of the damper provided in the distributor 102 may be adjusted so that the air supply amount in the first to third air supply ports 130 , 140 , 150 is different.

As air is supplied through the air supply ports 130 , 140 , and 150 by this process, the contaminated air can be quickly exhausted to the outside through the exhaust device 10 , thereby preventing the contaminated air from being diffused into the indoor space.

When the air is supplied through the air supply device 100 as described above, the amount of air supplied through the air supply ports 130 , 140 , and 150 will be described in more detail.

First, the amount of air supply in the first air inlet 130 and the second air inlet 140 will be described.

If the amount of air supplied through the first air inlet 130 and the second air inlet 140 is greater than necessary, the contaminated air may be diffused around the exhaust device 10 . Therefore, the air supply amount, which is the sum of the air supply amount of the first air inlet 130 and the air supply amount of the second air inlet 140, is set to be smaller than the exhaust amount, and the environment around the exhaust device 10 is formed in a negative pressure state, so that the contaminated air is diffused. can prevent As an example, the air supply amount that is the sum of the air supply amount of the first air supply port 130 and the air supply amount of the second air supply port 140 may be about 50% of the exhaust amount.

If, when air supply is made only in one of the first air inlet 130 and the second air inlet 140, the air supply amount of the one air inlet is smaller than the exhaust amount.

The air supply amount of the first air supply port 130 and the air supply amount of the second air supply port 140 may be the same or different.

First, when the distance between the first air inlet 130 and the exhaust device 10 is the same as the distance between the second air inlet 140 and the exhaust device 10, the first air inlet 130 ) to be the same as the amount of air supplied from the air supply and the amount of air supplied from the second air inlet 140 . When the air supply is made in this way, air supply is made uniformly on the left and right sides based on the center line C of the exhaust device 10 to prevent the contaminated air from leaking to the outside of the exhaust device 10 and spreading into the indoor space. can

In addition, when the distance between the first air inlet 130 and the exhaust device 10 is different from the distance between the second air inlet 140 and the exhaust device 10, the The air supply amount of the air supply port farther away from the exhaust device 10 is to be greater than the air supply amount of the close air supply port. When the air supply is made in this way, air supply can be made uniformly on the left and right sides with respect to the center line C of the exhaust device 10 .

In addition, the air supply amount of the second front and rear region (Z2) may be larger than the air supply amount of the first front and rear region (Z1). That is, the air supply amount of the third air supply port 150 can be set to be larger than the sum of the air supply amounts of the first and second air supply ports 130 and 140 . In this case, the air supply amount of the third air supply port 150 may be smaller than the exhaust amount. For example, the air supply amount of the third air supply port 150 may be set to be about 70% of the exhaust amount. In addition, the air supply amount of the third air supply port 150 may be equal to or greater than the exhaust amount. When the air supply amount is set in this way, the periphery of the exhaust device 10 is formed in a high pressure state compared to the first front and rear region Z1, so that the exhaust through the exhaust device 10 is smoothly performed. efficiency can be improved.

In addition, the sum of the air supply amount of the first to third air supply ports 130 , 140 , 150 provided in the first front and rear region Z1 and the second front and rear region Z2 may be greater than the exhaust amount of the exhaust device 10 . . When the air supply amount and the exhaust amount are set in this way, exhaust through the exhaust device 10 becomes smooth, so that the efficiency of the exhaust device 10 can be improved.

In addition, the air supply amount of each of the first and second air supply ports 130 and 140 provided in the first front and rear region (Z1) and the air supply amount of the third air supply port 150 provided in the second front and rear area (Z2) are Each can be made smaller than the exhaust amount of the exhaust device (10).

On the other hand, the air supplied through the air supply ports 130 and 140 provided in the first front and rear region Z1 first arrives at the exhaust device 10, and the air supplied through the air supply port provided in the second front and rear region Z1. can be configured to reach the exhaust system 10 later.

As an example for such a configuration, air is first supplied through the air supply ports 130 and 140 provided in the first front and rear area Z1, and through the air supply port 150 provided in the second front and rear area Z2. It can also be configured to supply air later. That is, in the initial stage of operation of the exhaust device 10 , air is supplied only through the first and second air supply ports 130 and 140 , thereby preventing the contaminated air from leaking to the outside of the exhaust device 10 , and negative pressure around the exhaust device 10 . to prevent the spread of polluted air into the indoor space. When the exhaust device 10 is operated in such a state for a predetermined time, the exhaust efficiency may be reduced due to negative pressure around the exhaust device 10 . Therefore, when a certain period of time has elapsed after the operation of the exhaust device 10 , air is supplied through the tertiary air supply port 150 so that exhaust from the exhaust device 10 can be smoothly performed.

As another example, air may be simultaneously supplied from the air supply ports 130 and 140 provided in the first front and rear region Z1 and the air supply ports 150 provided in the second front and rear region Z2.

On the other hand, if the cook increases the operating intensity of the exhaust device 10, such as changing from 1st stage to 2nd or 3rd stage, or lowers the operating intensity, such as changing from 2nd or 3rd stage to 1st stage, It is necessary to adjust the amount of air supplied to the instruments 130 , 140 , 150 .

In this case, when the information on the operating intensity of the exhaust blower 11 is transmitted from the exhaust device 10 and received by the exhaust amount information receiving unit 114 of the air supply device 100, the air supply amount adjusting unit 112 is the exhaust. The amount of air supplied by the air supply blower 120 may be adjusted so that air is supplied at an air supply amount corresponding to the operating intensity of the blower 11 .

As described above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above-described embodiments, and various modifications are made within the scope of the claims, the detailed description of the invention, and the accompanying drawings.
