Hereinafter, a range hood system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5, the present invention relates to a range hood system, by improving the structure of the hood for discharging smoke generated during cooking, applying two fans, and providing a non-powered rotating body to exhaust the air. It is about technology that can increase efficiency.

The range hood system includes: a first exhaust fan assembly 3 disposed above a heat source such as a gas stove and primarily sucking smoke generated from the heat source; a second exhaust fan assembly (5) disposed above the first exhaust fan assembly (3) to secondaryly discharge the sucked smoke; a non-powered rotating body 11 which is independently mounted on the first exhaust fan assembly 3 and removes foreign substances contained in smoke sucked by rotating by the wind generated during rotation; The first exhaust fan assembly 3 includes a foreign material collecting container 27 in which the foreign material attached by the non-powered rotating body 11 is stored by being concavely formed inside the first exhaust fan assembly 3 .

In more detail,

The first exhaust fan assembly 3 refers to a fan capable of sucking in and discharging a fluid, and includes, for example, a circulator. That is, the first exhaust fan assembly 3 includes a first case 1; a body 23 provided inside the first case 1 and on which a motor is mounted; At least one blade (Blade) 25 is radially disposed on the outer peripheral surface of the body (23).

Therefore, when the motor is driven, the blade 25 rotates to suck the smoke generated from the cook top (Cook top; 7).

At this time, since the blade 25 is disposed inside the first case 1 , smoke is sucked into the first case 1 .

Then, the smoke sucked into the first case 1 may be secondarily sucked by the second exhaust fan assembly 5 and discharged to the outside.

The second exhaust fan assembly 5 includes a second case 4 provided on the ceiling; and a second exhaust fan 13 disposed inside the second case 4 .

The second exhaust fan 13 means a fan for sucking in a fluid and discharging it to the outside, and includes, for example, a sirocco fan.

Accordingly, the sirocco fan rotates by the motor so that the smoke can be sucked in and discharged to the outside.

At this time, the second exhaust fan assembly 5 is integrally coupled to the upper portion of the first case 1 .

Accordingly, the smoke sucked into the first case 1 may be discharged to the outside through the second case 4 .

Of course, in the above description, the first case 1 and the second case 4 are integrally connected, but the present invention is not limited thereto and may be arranged independently of each other.

That is, as shown in FIG. 5 , the second case 4 is disposed on the ceiling, and the first case 1 is disposed below the second case 4 by a predetermined distance, so that they are arranged independently of each other.

In this case, the second exhaust fan assembly 5 may be disposed on the lower surface of the ceiling, but is not limited thereto, and may be separately disposed on the upper part of the ceiling, the roof, or the outside of the building.

And, by adjusting the rotation speed of the first exhaust fan assembly 3 and the rotation speed of the second exhaust fan assembly 5, the second exhaust fan assembly 5 is lowered than the amount of air sucked into the first exhaust fan assembly 3 . Backflow can be prevented by increasing the amount of air exhausted through the

On the other hand, the non-powered rotating body 11 is coupled to the lower inner side of the first exhaust fan assembly 3 so that it rotates when the first exhaust fan 25 rotates.

This non-powered rotating body 11 includes a circular frame 17; A plurality of rotary blades 18 connected in the inner radial direction in the circular frame 17 and; a center plate 19 to which a plurality of rotary blades 18 are connected; a connecting shaft 21 protruding from the upper portion of the center plate 19 and coupled to the main body 23 of the first exhaust fan assembly 3 so as to be idling; It is disposed between the plurality of rotor blades 18 and includes a screen 20 for filtering moisture or contaminants.

In this non-powered rotating body 11,

The connecting shaft 21 is rotatably connected to the bottom surface of the main body 23 of the first exhaust fan assembly 3 by the bearing B. Therefore, even when the blade 25 of the first exhaust fan assembly 3 rotates, the non-motorized rotating body 11 does not rotate in conjunction, and the wind generated by the rotation of the blade 25 is applied to the non-powered rotating body 11 . When reached, it rotates independently.

At this time, since smoke is being sucked into the first case 1 by the suction force of the first exhaust fan assembly 3 , the sucked smoke passes through the non-powered rotating body 11 .

And, the rotary blade 18 of the non-powered rotating body 11 may have a straight shape as shown in FIG. 2 , or may have a curved shape as shown in FIG. 4 .

When the rotary blade 18 has a curved shape, the rotational direction of the rotary blade 18 may also be varied according to the direction of the curve.

That is, when the curved direction is clockwise, the rotary blade 18 also rotates clockwise, and on the contrary, when the curved direction is counterclockwise, the rotary blade 18 also rotates counterclockwise.

At this time, setting the curved direction in a clockwise or counterclockwise direction is to couple the upper surface of the rotary blade 18 in the direction of the main body of the second exhaust fan assembly, or reverse the rotary blade 18 up and down to combine the lower surface in the body direction. can be determined by

On the other hand, while the smoke sucked by the first exhaust fan assembly 3 passes through the non-powered rotating body 11, foreign substances such as moisture, dust, and oil contained in the smoke are removed from the plurality of rotary blades 18 and the screen ( 20) is in contact.

In addition, foreign substances in contact with the screen 20 and the rotor blades 18 are dispersed radially outwardly by the centrifugal force of the rotor blades 18 , and the dispersed foreign substances are collected by the foreign substances container 27 .

On the other hand, the non-powered rotating body 11 may be disposed to be inclined at a predetermined angle (θ). That is, as shown in FIG. 3 , the connection shaft 21 coupled to the lower portion of the first exhaust fan assembly 3 is tilted at a predetermined angle (θ), or the angle (θ) of the circular frame 17 is tilted. Accordingly, the non-powered rotating body 11 can be configured to be inclined.

In this way, when the non-powered rotating body 11 is rotated in a state inclined at a predetermined angle (θ), the foreign substances contained in the smoke are collected by the foreign material container 27, so that the foreign substances are cooked in the lower cooktop 7 can be prevented from falling.

And, the angle of the rotary blade 18 of the non-powered rotating body 11 may be inclined to a certain angle (θ). That is, the inclined angle θ of the plurality of rotary blades 18 is appropriately adjusted, or the interval between the rotary blades 18 is adjusted.

As such, by adjusting the angle θ of the rotary blade 18 or adjusting the interval, the noise can be reduced by reducing the air resistance generated during the rotation of the non-powered rotor 11 .

Meanwhile, in the above, foreign substances contained in the smoke are scattered and removed in the radial direction by the non-powered rotating body, but the present invention is not limited thereto, and a power-type rotating body may also be included.

That is, a separate motor is mounted on the lower portion of the main body 23 of the first exhaust fan assembly 3 and the connecting shaft 21 of the rotary blade 18 is connected to the motor.

Accordingly, by independently rotating the rotor blades by driving the motor, foreign substances can be adsorbed and scattered in the radial direction.

On the other hand, the foreign material container 27 is disposed inside the lower frame 17 of the first case (1). The foreign material container 27 has a concave upper side and is formed in a circular shape along the frame 17 of the first case 1 .

Therefore, the foreign material dispersed in the outward direction by the plurality of rotary blades 18 may be collected by the foreign material container 27 .

In this way, foreign substances contained in the smoke sucked into the first case (1) are dispersed outwardly by the plurality of rotating blades (18) in the process of passing through the non-powered rotating body (11) and collected in the foreign material container (27). can be

In addition, the foreign material container 27 has a structure detachably coupled to the lower portion of the first case (1). Therefore, when more than a certain amount of foreign matter is collected in the foreign material container 27 , only the foreign material can be removed by separating the foreign material container 27 .

In addition, when cooking is not performed, the first exhaust fan assembly 3 may be stopped and only the second exhaust fan assembly 5 may be rotated. In this way, when only the second exhaust fan assembly 5 is rotated, the air in the room is discharged to the outside to perform ventilation.

On the other hand, a fire extinguisher (S) is mounted inside the second case (4). And, the fire extinguisher (S) has a structure that interlocks with the temperature sensor of the cooktop (7).

Therefore, when it is determined that the temperature sensed by the temperature sensor is above a certain temperature, the control unit can suppress the fire by transmitting a signal to the fire extinguisher (S) and operating it.

In the above, it has been described that the first and second exhaust fan assemblies 3 and 5 are arranged as one set, but the present invention is not limited thereto, and the second exhaust fan assembly 5 is omitted and the first exhaust fan is not limited thereto. It is also possible to attach only the assembly 3 to the ceiling. At this time, the rotating body 11 and the foreign material container 27 are maintained as they are.

Hereinafter, an operation process of the range hood system according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 5 , when cooking is performed on the cooktop 7, smoke containing moisture, oil, foreign substances, etc. is generated, and the range hood system is operated to discharge the smoke to the outside. .

In more detail, the first and second exhaust fan assemblies 3 and 5 are driven by turning on the switch of the control unit.

That is, when the first exhaust fan assembly 3 such as a circulator is driven, the blade 25 rotates to primarily suck the smoke generated from the cooktop 7 , and the smoke generated by the cooktop 7 is sucked into the inside of the first case 1 . Smoke may be discharged to the outside by being sucked secondarily by the second exhaust fan 13 such as a sirocco fan.

As described above, by rotating the first exhaust fan assembly 3 and the second exhaust fan assembly 5 twice, smoke generated during the cooktop 7 can be efficiently discharged.

In addition, a non-powered rotating body 11 is coupled to the lower portion of the first exhaust fan assembly 3 so that it rotates with the wind generated when the first exhaust fan assembly 3 rotates, thereby removing foreign substances contained in the smoke. can

In addition, since smoke is sucked into the interior of the first case 1 by the suction force of the first exhaust fan assembly 3 , the sucked smoke passes through the non-powered rotating body 11 . Accordingly, in the process of the smoke passing through the non-powered rotating body 11 , foreign substances such as moisture, dust, and oil contained in the smoke come into contact with the plurality of rotor blades 18 and the screen 20 .

In addition, foreign substances in contact with the screen 20 and the rotor blades 18 are dispersed radially outwardly by the centrifugal force of the rotor blades 18 , and the dispersed foreign substances are collected by the foreign substances container 27 .

Through this process, the smoke generated from the cooktop 7 can be effectively discharged through the range hood system.
