The supplied air flows to the other half region of the front surface H1 and the second side surface H3.

Referring to FIG. 6, the minimum and maximum angles of the first angle for installing the air supply holes 130 and 140 will be described with reference to the top view. Hereinafter, the first air supply unit 130 will be described, but the same applies to the second air supply unit 140.

The first angle refers to an angle formed by the air supply direction of the first air supply unit 130 with respect to the straight line HL parallel to the front surface of the exhaust device 10.

The horizontal length of the exhaust device 10 was defined as W, and the vertical length of the exhaust device 10 was defined as D. The distance between the exhaust device 10 and the first air supply 130 is defined as L.

In order to calculate the case where the first air supply unit 130 is installed at the minimum angle, the horizontal length W of the exhaust device 10 is divided into four parts, and the corners of one side edge area are connected in the quartered area. Draw a diagonal line DL1. A straight line PL1 is drawn starting from the first air supply 130 and orthogonal to the diagonal line DL1.

In addition, in order to calculate the case where the first air supply unit 130 is installed at the maximum angle, a diagonal line DL2 connecting the diagonal edges of the exhaust device 10 is drawn. A straight line PL2 is drawn starting from the first air supply 130 and orthogonal to the diagonal line DL2.

The minimum angle θ1 in the first angle may be defined by Equation 1 below.

 The minimum angle θ1 is a minimum at which air supplied from the first air supply port 130 is supplied to all of the first side surfaces H2 of the exhaust device 10, and may be supplied to at least a portion of the front surface H1. Means the angle condition.

The maximum angle θ2 in the first angle may be defined by Equation 2 below.

The maximum angle θ2 may be supplied to the air supplied from the first air supply 130 to at least half of the front surface H1 of the exhaust device 10, and may be supplied to all of the first side surfaces H2. That means the maximum angle condition.

7 and 8, the minimum and maximum angles of the second angle for installing the air supply ports 130 and 140 will be described with reference to the side views.

Referring to FIG. 7A, the first air supply 130 is relatively small as an angle θ between a straight line LL (ceiling surface) parallel to the ceiling and the guide 131 of the first air supply 130. The installed state is shown at an angle.

Referring to FIG. 7B, the first air supply 130 is installed at a relatively large angle as an angle θ between a straight line LL parallel to the ceiling and the guide 131 of the first air supply 130. Status is shown.

Referring to FIG. 8, the minimum and maximum angles of the second angle for installing the air supply holes 130 and 140 will be described with reference to the side view. Hereinafter, the first air supply unit 130 will be described, but the same applies to the second air supply unit 140.

The second angle is a straight line LL parallel to the ceiling on which the first air supply unit 130 is installed. Means the angle between the guide 131 in the air supply direction of the first air supply 130.

The distance between the first air supply 130 and the exhaust system 10 is defined as L, the ceiling and the lower end of the exhaust system 10 is defined as x1, and the ceiling and the top of the sink 30 as x2 define.

The minimum angle θ3 in the second angle may be defined by Equation 3 below.

The maximum angle θ4 in the second angle may be defined by Equation 4 below.

As described above, the installation angle of the air supply ports 130 and 140 in the vertical direction based on the side view (that is, the angle of the guide 131) is between the minimum angle θ3 and the maximum angle θ4, so that the exhaust air is based on the ceiling. Applicable to various installation heights of the device 10, it is possible to prevent the spread of contaminated air by supplying the air supplied to the sink 30.

A control configuration of the air supply device 100 according to the present invention will be described with reference to FIG. 9.

The air supply device 100 includes an air supply fan 120 for supplying air to the room through the air supply mechanisms 130, 140, 150, 160, 170, and 180, and a controller 110 for controlling the operation of the air supply blower 120.

The air supply blower 120 sucks outdoor air and supplies the air to the room. In this case, the air supply blower 120 may be configured to suck air from another indoor space instead of outdoor air to supply to the kitchen.

The apparatus may further include an exhaust capacity information storage unit 113 for storing displacement information according to the operation of the exhaust gas, and an displacement information receiving unit 114 for receiving displacement information according to the operation of the exhaust apparatus 10.

The air supply amount adjusting unit 112 may adjust the air supply amount supplied to the first to third air supply mechanisms 130, 140, and 150 by adjusting the opening degree of the damper provided in the distributor 102 described above.

In addition, the opening degree of the damper may be set in advance to a certain opening degree when the air supply device 100 is first installed. In this state in which the damper opening degree is set, the air supply amount adjusting unit 112 may drive the air supply blower 120 at a set rotation speed. By such a method, the air supply amount supplied to the first to third air supply mechanisms 130, 140, and 150 may be supplied as a predetermined air supply amount.

In addition, when the air supply device 100 is first installed, the opening degree of the damper is set, and the rotation speed of the air supply blower 120 is varied, and whether the desired air supply amount is supplied from each of the first to third air supply ports 130, 140, and 150. You can check it. In this case, the air supply amount in the first to third air supply port (130, 140, 150) will vary depending on the installation state of the duct, such as the length of the duct, the degree of bending the duct. When the air supply amount is confirmed in this way, the rotation speed of the air supply blower 120 is set when the desired air supply amount is supplied. When the rotation speed of the air supply blower 120 is set to a fixed value in this way, the air supply blower 120 is operated at the set speed during air supply.

The displacement information storage unit 113 may store information on the displacement of the exhaust apparatus 10. The information on the displacement may be input and stored in advance in the displacement information storage unit 113, or may be configured to receive information on the displacement from the exhaust apparatus 10.

The exhaust device 10 and the air supply device 100 may communicate with each other by a communication unit (not shown). The displacement of the exhaust device 10 can be varied by the cooker adjusting the operating strength in the exhaust device 10. The information about the displacement is received by the displacement information receiver 114 and stored in the displacement information storage 113, and the air supply apparatus 100 may adjust the air supply amount according to the stored displacement information.

A case in which air curtains AC1, AC2, and AC3 are formed in the exhaust device 10 will be described with reference to FIG. 10.

Air curtains AC1, AC2, and AC3 are formed on the front surface H1, the first side surface H2, and the second side surface H3 of the exhaust device 10 by injecting air downward in the range 20. Can be.

An air injection unit (not shown) may be provided to inject air to form the air curtains AC1, AC2, and AC3. An 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 using the air supplied from the air supply blower 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 to surround the front surface H1, the first side surface H2, and the second side surface H3 of the exhaust device 10.

In addition, the air curtains AC2 and AC3 may be formed only on both side surfaces H2 and H3 except for the air curtain AC1 of the front surface H1 formed downward.

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 the side opposite to the position where the first and second air supply mechanisms 130 and 140 are formed among the first side surface H2 and the second side surface H3.

Control for forming the air curtain (AC1, AC2, AC3) may be made in the exhaust device 10, may be made in the air supply device (100).

In the case of controlling by the exhaust device 10, the control unit (not shown) of the exhaust device 10 generates a control signal for operating the air injector and the air curtains AC1 and AC2. , AC3).

In addition, when the air supply device 100 is integrally provided in the exhaust device 10, the air supply (AC1, AC2, AC3) at the same time as the air supply to the air supply port (130, 140, 150) from the exhaust device 10 The air supply blower may be operated to form.

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, and 150, and by using the air supplied from the air supply blower 120. The air curtains AC1, AC2, and AC3 may be formed.

Also, the air supply unit AC1, AC2, AC3 may be formed by transmitting a control signal to the exhaust device 10 by wire / wireless communication of the communication unit in the air supply device 100.

When the air curtains AC1, AC2, and AC3 are formed in this way, the polluted air can be prevented from spreading outside the exhaust device 10, thereby improving the exhaust efficiency.

A case in which 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 up and down on at least one side of the exhaust device 10. When the blocking plate 16 is lowered to block at least a portion of the lower space of the exhaust device 10, contaminated air may be prevented from leaking to the outside of the exhaust device 10 and spreading to the indoor space.

When the blocking plate 16 is provided on both side surfaces H2 and H3 of the exhaust device 10, it may cause inconvenience to the cooker. Therefore, it is preferable that only one side of the exhaust device 10 is provided.

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

The control method of the air supply apparatus by this invention is demonstrated.

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

According to the operation of the exhaust device 10, the air supply device 100 is operated manually or automatically. That is, when the 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 predetermined fixed speed to supply the air supply 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 be operated. In order to adjust the amount of air supply in the air supply control unit 112 may change the number of revolutions of the air supply blower 120. In addition, the opening degree of the damper provided in the distributor 102 may be adjusted to different the air supply amount from the first to third air supply mechanisms 130, 140, and 150.

By supplying air through the air supply ports 130, 140, and 150 by such a process, the polluted air can be quickly exhausted to the outside through the exhaust device 10, thereby preventing the polluted air from being diffused into the indoor space.

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

First, the air supply amounts in the first air supply unit 130 and the second air supply unit 140 will be described.

If the air supply amount supplied through the first air supply unit 130 and the second air supply unit 140 is more than necessary, contaminated air may diffuse around the exhaust device 10. Therefore, by supplying the air supply amount of the air supply amount of the first air supply unit 130 and the air supply amount of the second air supply unit 140 to be smaller than the amount of exhaust air, the contaminated air is diffused by forming the vicinity of the exhaust device 10 in a negative pressure state. Can be prevented. For example, the air supply amount obtained by adding the air supply amount of the first air supply unit 130 and the air supply amount of the second air supply unit 140 may be about 50% of the exhaust gas amount.

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

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

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

In addition, when the distance between the first air supply 130 and the exhaust device 10 is different from the distance between the second air supply 140 and the exhaust device 10 from the exhaust device 10 The air supply amount of the air supply port is far from the air supply unit so that the distance from the exhaust device 10 is larger than the air supply amount of the close air supply port. When the air supply is made in this way, the air supply may 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 regions Z2 may be larger than the air supply amount of the first front and rear regions Z1. That is, the air supply amount of the third air supply unit 150 may be set larger than the sum of the air supply amounts of the first and second air supply units 130 and 140. In this case, the air supply amount of the third air supply port 150 can be made smaller than the exhaust amount. For example, the air supply amount of the third air supply unit 150 may be set to about 70% of the exhaust amount. In addition, the air supply amount of the third air supply unit 150 may be equal to or larger than the exhaust amount. When the air supply amount is set in this way, the surroundings of the exhaust apparatus 10 are formed at a higher pressure than the first front and rear regions Z1, so that the exhaust gas is smoothly exhausted through the exhaust apparatus 10. The efficiency can be improved.

In addition, the sum of the air supply amounts of the first to third air supply mechanisms 130, 140, and 150 provided in the first front and rear regions Z1 and the second front and rear regions Z2 may be larger than the exhaust volume of the exhaust device 10. . When the air supply amount and the exhaust amount are set in this way, the exhaust gas is smoothly exhausted through the exhaust apparatus 10, thereby improving the efficiency of the exhaust apparatus 10.

In addition, the air supply of each of the first and second air supply ports 130 and 140 provided in the first before and after zone Z1 and the air supply of the third air supply unit 150 provided in the second before and after zone Z2 may be Each of the exhaust apparatus 10 may be smaller than the displacement of the exhaust apparatus 10.

Meanwhile, the air supplied through the air supply ports 130 and 140 provided in the first front and rear zone Z1 reaches the exhaust device 10 first, and the air supplied through the air supply port provided in the second front and rear regions Z1. Can be configured to reach the exhaust device 10 later.

As an example for such a configuration, the air supply is made first through the air supply ports 130 and 140 provided in the first front and rear regions Z1, and the air supply unit 150 provided in the second front and rear regions Z2. It can also be configured to supply air later. That is, in the initial stage of operation of the exhaust device 10, the air contaminated outside the exhaust device 10 is prevented from leaking by supplying air only through the first and second air supply mechanisms 130 and 140, and the negative pressure around the exhaust device 10 is reduced. This prevents contaminated air from diffusing into the indoor space. In this state, when the exhaust device 10 is operated for a predetermined time, the exhaust efficiency may decrease due to the negative pressure around the exhaust device 10. Therefore, when a predetermined time elapses after the operation of the exhaust system 10, the exhaust gas may be smoothly exhausted by supplying air through the third air supply unit 150.

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

On the other hand, if the cooker increases the operating strength, such as changing the operating strength of the exhaust system 10 from the first stage to the second stage or the third stage, or lowers the operating strength, such as changing from the second stage or the third stage to the first stage, It is necessary to adjust the air supply amount of the mechanism (130, 140, 150).

In this case, when information on the operating strength 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 may exhaust the exhaust air. The air supply amount in the air supply blower 120 may be adjusted to supply air to the 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 are made within the scope of the claims and the detailed description of the invention and the accompanying drawings. It is possible to carry out by this and this also belongs to the present invention.
