The first air supply port 130 and the second air supply port 140 are provided in front of the exhaust device 10 and outside the side surfaces of the exhaust device 10. In addition, the third air supply port 150 is provided at a position farther from the exhaust device 10 than the first and second air supply ports 130 and 140.

Reference numeral 20 denotes an 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 stove 20 is installed under the exhaust device 10. By drawing an imaginary straight line extending from the front surface H1 and both side surfaces H2 and H3 of the exhaust device 10, two areas A1 and A2 indicated by hatching can be set.

The direction in which the third air supply port 150 to be described later is located from 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, the area surrounded by a straight line extending left from the front surface H1 and a straight line extending downward from the first side surface H2 is referred to as a first left and right area A1, and A region surrounded by a straight line extending from H1 to the right 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 areas in front of the front surface H1 of the exhaust device 10, and are respectively formed outside of both sides H2 and H3 of the exhaust device 10. to be.

A first air supply port 130 is provided in the first left and right areas A1, and a second air supply port 140 is provided in the second left and right areas A2.

When the first supply port 130 and the second supply port 140 are provided in such a position to supply air during cooking, contaminated air generated during cooking is efficiently transferred to the outside through the exhaust device 10. It can be exhausted and contaminated air can be prevented from spreading into the indoor space.

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

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

When food is cooked in the range 20, contaminated air flows upward, and some of the contaminated air flowing in this way is discharged to the outside through the exhaust device 10, but the rest of the It flows in the direction of the ceiling of the kitchen through the front surface H1 and both sides H2 and H3, and may diffuse into the indoor space.

When the air supplied through the first supply port 130 and the second supply port 140 is directed toward the front side (H1) and side surfaces (H2, H3) of the exhaust device 10 as described above, the range 20 Contaminated air flowing upward from the top can be prevented from flowing in the ceiling direction along the front surface H1 and both sides H2 and H3, which are the outside of the exhaust device 10. Therefore, it is possible to prevent the contaminated air from spreading to the indoor space.

In addition, the cooker cooks while standing in front of the front surface H1 of the range 20, and the first supply port 130 or/and the second supply port 140 are on both sides H2 of the range 20. When located in the third area (A3) formed between the planes extending forward from H3), the air supplied from the first supply port 130 or the second supply port 140 affects the cooker and cooks It can cause discomfort. Therefore, by providing the first air supply port 130 and the second air supply port 140 in the first left and right regions A1 or the second left and right regions A2 outside the third region A3, the air supplied to the cooker It can be prevented from affecting.

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

Among the air supplied from the first supply port 130, the air toward the front surface H1 and the air supplied by the second supply port 140 toward the front surface H1 are the front surface (H1) of the range 20. The first air supply port 130 and the second air supply port 140 may be supplied in directions such that an overlapping section O is formed by overlapping a certain section at the central portion of ). When the overlapping section O is formed in this way, it is possible to effectively prevent contaminated air from leaking in the ceiling direction while riding the front surface H1 of the exhaust device 10.

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

When the linear distance is the same as described above, by setting the supply amount of air supplied through the first air supply port 130 and the air supply amount of air supplied through the second air supply port 140 to be the same, the contaminated Air can be smoothly exhausted to the outside without being drawn to either side of the exhaust device 10.

In addition, when the linear distance is the same, the first air supply 130 and the second air supply 140 are provided at the same position in the front and rear direction of the exhaust device 10 from the front of the exhaust device 10. Includes cases where it becomes. That is, a first distance (D1) between the center of the first supply port 130 and the front surface of the exhaust device 10, and the center of the second supply port 140 and the front surface of the exhaust device 10 This is the case where the second distance D2 between them is the same.

In this case, when the first air supply port 130 and the second air supply port 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).

As the linear distance between the first air supply port 130 and the second air supply port 140 and the exhaust device 10 increases, the air resistance until it reaches the exhaust device 10 by being discharged from the air supply ports 130 and 140 The closer the linear distance is, the less air resistance is received.

Therefore, when the linear distance between the first supply port 130 and the exhaust device 10 and the linear distance between the second supply port 140 and the exhaust device 10 are different, from the exhaust device 10 It is possible to set so that the amount of air supplied from the air supply port having a distant linear distance from the exhaust device 10 is greater than the air supply amount of the air supply port near the air supply device 10. As a result, the air supplied from the first air supply port 130 and the second air supply port 140 may uniformly reach the exhaust device 10.

When air is supplied from the air supply ports 130 and 140 toward the exhaust device 10 in this way, even if the exhaust device 10 is operated at a low intensity, pollutants are smoothly exhausted to the outside through the exhaust device 10 to prevent 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.

On the other hand, the first air supply port 130 and the second air supply port 140 are provided in a first front and rear area Z1 formed at a predetermined distance from the front surface H1 of the exhaust device 10, and the exhaust device ( A third air supply port 150 for supplying air may be provided in the second before and after area Z2 formed at a distance from the front surface H1 of 10) than the first before and after area Z1.

The first supply port 130 and the second supply port 140 provided in the first front and rear area Z1 are contaminated around the exhaust device 10 by directing the supplied air toward the exhaust device 10. It can prevent air from spreading out.

The third supply port 150 provided in the second front and rear area Z2 is provided to face the front surface H1 of the exhaust device 10, so that the air supplied from the third supply port 150 is exhausted. It may be provided to supply air toward (10). In addition, one of the third air supply ports 150 may be provided on the center line C of the exhaust device 10, and other air supply ports may be further provided in addition to the third air supply port 150. . In addition, the air supplied from the third supply port 150 may be configured not to face the exhaust device 10 but to face other directions such as the floor or the wall, and may be directed in all directions along the entire circumference of the third air supply port 150. It can also be configured to do.

In the above, only the first before and after areas Z1 and the second before and after areas Z2 are divided, but a fourth supply port (not shown) and a fifth supply port (not shown) are provided in front of the third supply port 150. And the fourth supply port is provided in a third before and after area (not shown) formed in front of the second before and after area Z2, and the fifth supply port is formed in front of the third before and after area. In addition to the first and second front and rear areas Z1 and Z2, such as provided in an area (not shown), a plurality of front and rear areas and a plurality of air supply ports may be further provided.

In addition, the first air supply 130 and/or the second air supply 140 may be located between virtual straight lines extending from both side surfaces H2 and H3, respectively. In this case, the air supplied from the first supply port 130 or the second supply port 140 is not directly supplied toward the first side H2 or the second side H3, but the first side H2 ), or the space to the right of the second side H3.

In addition, the opening degree of the damper may be set in advance to a predetermined opening degree when the air supply device 100 is first installed. In the state where the opening degree of the damper is set, the air supply amount control unit 112 may drive the air supply blower 120 at the set rotational speed. In this way, the amount of air supplied to the first to third air supply ports 130, 140, and 150 may be supplied at the set air supply amount.

In addition, when installing the air supply device 100 for the first time, the opening degree of the damper is set and the number of rotations of the air supply blower 120 is varied, while determining whether the desired air supply amount is supplied from each of the first to third air supply ports 130, 140, and 150. I can confirm. In this case, the amount of air supplied from the first to third air supply ports 130, 140, 150 varies depending on the installation state of the duct, such as the length of the duct and the degree of bending the duct. When the amount of air supply is confirmed in this way, the number of revolutions of the air supply fan 120 at the time when the desired air supply amount is supplied is set. When the number of revolutions of the air supply fan 120 is set to a fixed value, the air supply fan 120 is operated at the set number of revolutions during supply.

The air injection unit for forming the air curtains AC1, AC2 and AC3 may be separately provided in the exhaust device 10. In addition, when the air curtains AC1, AC2, and AC3 are formed by using the air supplied from the air supply fan 120 provided in the air supply device 100, the air supply blower 120 functions as an air injection unit.

The air curtains AC1, AC2, and AC3 may be configured to be formed in all three directions so as to surround the front surface H1, the first side surface H2, and the second side surface H3 of the exhaust device 10.

In addition, it is possible to form the air curtains AC2 and AC3 only on both side surfaces H2 and H3 except for the air curtain AC1 of the front surface H1 formed in the downward direction.

In addition, the air curtain may be formed in only one of the front surface H1, the first side surface H2, and the second side surface H3 of the exhaust device 10. In this case, it is preferable to form an air curtain on a side of the first side surface H2 and the second side surface H3 opposite to the position where the first and second supply ports 130 and 140 are formed.

Control for forming the air curtains AC1, AC2, and AC3 may be performed in the exhaust device 10 or in the air supply device 100.

In the case of control by the exhaust device 10, a control signal for activating the air injection unit is generated by the control unit (not shown) of the exhaust device 10 together with the operation of the exhaust device 10, and the air curtains AC1 and AC2 , AC3) is formed.

In the case of controlling by the air supply device 100, the air supply fan 120 is operated in the air supply device 100 to supply air through the air supply ports 130, 140, 150, and the air supplied from the air supply fan 120 is used. The air curtains AC1, AC2, AC3 may be formed.

In addition, the air supply device 100 may transmit a control signal to the exhaust device 10 through wired/wireless communication of the communication unit to operate the air injection unit to form the air curtains AC1, AC2, AC3.

When the air curtains AC1, AC2, and AC3 are formed in this way, it is possible to improve the exhaust efficiency by preventing contaminated air from spreading to the outside of the exhaust device 10.

A case where the blocking plate 16 is provided in the exhaust device 10 will be described with reference to FIG. 11.

The blocking plate 16 may be provided in a structure that is movable in a 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, contaminated air can be prevented 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 cooker. Therefore, it is preferable that it is provided only on one side of the exhaust device 10.

In addition, when the air supply ports 130 and 140 are provided only on 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 system The blocking plate 16 may be provided on a side opposite to the position where the air supply ports 130 and 140 are provided among both side surfaces H2 and H3 of (10). When configured in this way, the blocking plate 16 prevents the air contaminated by the air supplied from the supply ports 130 and 140 from being pushed out of the lower space of the exhaust device 10 in the direction opposite to the direction in which the 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 manually or automatically operated to exhaust the contaminated 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 receiver 111, the air supply blower 120 is operated.

In this case, the air supply blower 120 may be operated at a fixed rotational speed set in advance to supply the air supply amount required by the first to third air supply devices 130, 140, 150, and the first to third air supply devices 130, 140, 150 In order to adjust the amount of air supply in ), the number of revolutions of the air supply blower 120 may be varied in the air supply amount control unit 112. In addition, the opening degree of the damper provided in the distributor 102 may be adjusted in order to make the amount of air supplied from the first to third air supply ports 130, 140, and 150 different.

By supplying air through the supply ports 130, 140, and 150 by this process, contaminated air can be quickly exhausted to the outside through the exhaust device 10, thereby preventing the contaminated air from spreading to the indoor space.

When 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 supplied from the first air supply port 130 and the second air supply port 140 will be described.

If the amount of air supplied through the first air supply port 130 and the second air supply port 140 is greater than necessary, contaminated air may diffuse around the exhaust device 10. Therefore, the amount of air supplied by 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 is made smaller than the amount of exhaust air, so that the contaminated air is diffused by forming the surroundings of the exhaust device 10 in a negative pressure state. Can be prevented. For example, the amount of air supplied by 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 air is supplied only from one of the first air supply port 130 and the second air supply port 140, the air supply amount of one of the air supply ports is set to be smaller than the exhaust amount.

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

First, when the distance between the first air supply port 130 and the exhaust device 10 is the same as the distance between the second air supply port 140 and the exhaust device 10, the first air supply port 130 ) So that the amount of air supplied from the second air supply port 140 and the amount of air supplied from the second air supply port 140 are the same. When air supply is made in this way, supply is uniformly supplied on the left and right sides based on the center line (C) of the exhaust device 10, thereby preventing contaminated air from leaking out of the exhaust device 10 and spreading into the indoor space. I can.

In addition, when the distance between the first air supply port 130 and the exhaust device 10 is different from the distance between the second air supply port 140 and the exhaust device 10, from the exhaust device 10 The air supply amount of the air supply port with a distance of is greater than the air supply amount of the air supply air supply at a distance from the exhaust device 10. When the air supply is performed in this way, air supply can be uniformly formed on the left and right sides based on the center line C of the exhaust device 10.

In addition, the amount of air supplied in the second before and after region Z2 may be greater than the amount of air supplied in the first before and after region Z1. That is, the air supply amount of the third air supply port 150 may be set to be larger than the sum of the air supply amount of the first and second air supply ports 130 and 140. In this case, the supply air 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 supply air amount is set in this way, the area around the exhaust device 10 is formed at a higher pressure than that of the first front and rear area Z1, so that the exhaust through the exhaust device 10 is smoothly performed, and the exhaust device 10 Efficiency can be improved.

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

In addition, the supply amount of each of the first and second supply ports 130 and 140 provided in the first before and after region Z1 and the supply amount of the third supply hole 150 provided in the second before and after region 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 before and after region Z1 reaches the exhaust device 10 first, and the air supplied through the supply ports provided in the second before and after region. Can be configured to reach the exhaust device 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 before and after region Z1, and through the supply air supply 150 provided in the second before and after region Z2. It can also be configured to supply air later. That is, at the beginning of operation of the exhaust device 10, air is supplied only through the first and second air supply ports 130 and 140 to prevent leakage of contaminated air to the outside of the exhaust device 10, and negative pressure around the exhaust device 10 To prevent the contaminated air from spreading into the indoor space. When the exhaust device 10 is operated in such a state for a certain period of time, the exhaust efficiency may be lowered due to the negative pressure around the exhaust device 10. Therefore, when a certain time elapses after the exhaust device 10 is operated, air is supplied through the third air supply mechanism 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 before and after region Z1 and the air supply holes 150 provided in the second before and after region Z2.

On the other hand, if the cooker increases the operation strength, such as changing the operation strength of the exhaust device 10 from the first stage to the second stage or the third stage, or decreases the operation strength, such as changing from the second stage or the third stage to the first stage, It is necessary to adjust the amount of air supplied to the devices 130, 140, 150.

In this case, when information on the operation strength of the exhaust blower 11 is transmitted from the exhaust device 10 and is received by the exhaust amount information receiving unit 114 of the air supply device 100, the air supply amount adjusting unit 112 The amount of air supplied from the air supply blower 120 may be adjusted so that air supply is performed at an air supply amount corresponding to the operating strength 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 within the scope of the claims, the detailed description of the invention, and the accompanying drawings. It is possible to do so and this also belongs to the present invention.
