Description

Cyclone air interchanger

Technical Field

The invention relates to a cyclone ventilation device. In particular, the present invention relates to a cyclone ventilator used in a factory, a home, a restaurant, or the like, which generates a large amount of pollutants.

Background

Generally, exhaust devices such as ventilators are mainly used in factories, homes, restaurants, and the like, which produce a large amount of pollutants. The ventilation device is mainly used when a part of a pollution source exists on the ground far from the exhaust pipe, when the exhaust pipe cannot be installed around the pollution source due to the existence of another structure, or when the pollution source is instantaneously generated or has a high frequency.

Specifically, a kitchen ventilator used in restaurants and homes, an industrial ventilator used in factories, a bathroom ventilator used in bathrooms for the purpose of emitting odor and moisture, and the like are configured to have a simple structure including a fan having a propeller shape and a housing for housing the fan.

Therefore, the efficiency of the exhaust will be compromised if the source of pollution is remote or there is a large amount of pollution. Therefore, a new structure of the ventilation device is required which can concentrate the exhaust force on the pollution source and improve the exhaust efficiency.

As shown in fig. 1 to 8, the cyclone ventilation apparatus 10 of the exemplary embodiment may include a rotating fan 100 and an air conditioning fan. The rotary fan 100 may rotate about a rotation shaft 110 to suck foreign substances. The rotating fan 100 may have a propeller shape.

For example, the foreign matter may be located below the cyclone ventilation apparatus 10, and the foreign matter may be discharged from a pollution source. The foreign matter may be industrial foreign matter generated in the gold plating process. In contrast, the foreign matter may be foreign matter generated during cooking in a kitchen.

The air conditioner fan surrounds the rotary fan 100 and is rotatable around the rotation shaft 110 as well as the cyclone fan 100. For example, the cyclone fan 100 and the above-described air conditioning fan may be rotated in the same direction. In contrast, the cyclone fan 100 and the above air conditioner fan may be rotated in different directions.

In addition, the cyclone fan 100 and the above air conditioner fan may be rotated at the same speed. In contrast, the cyclone fan 100 and the above air conditioner fan may be rotated at different speeds. For example, the cyclone fan 100 and the air conditioning fan may be rotated by the same motor (not shown). In contrast, the cyclone fan 100 and the air conditioner fan may be rotated by different motors (not shown).

The air conditioner fan may include an inner circumferential vane 210, an outer circumferential vane 220, a plurality of radius vanes 200, a first circumferential vane 300, a second circumferential vane 310, a third circumferential vane 320, a fourth circumferential vane 330, a plurality of first auxiliary radius vanes 340, an upper cover 400, and a lower cover 500.

The inner circumferential blade 210 may be elongated in the circumferential direction (θ) centering on the rotation shaft 110. The inner circumferential blade 210 may surround the rotating fan 100 and have a hollow cylindrical shape. The foreign matter is sucked by the cyclone generated by the rotary fan 100, passes through the inner circumferential blades 210, and is discharged to a ventilation duct (not shown).

The outer circumferential vanes 220 may be spaced apart from the inner circumferential vanes 210 in the radial direction (r). In addition, the outer circumferential blade 220 may be elongated in the circumferential direction (θ) and have a hollow cylindrical shape.

The outer circumferential vane 220 includes first to fourth

circumferential vanes

300, 310, 320 and 330 and a first auxiliary radius vane 340, which will be described later, and constitutes the appearance of the air conditioner fan.

The radius blades 200 may each connect an inner circumferential blade 210 and an outer circumferential blade 220. Each of the radius blades 200 may be elongated in the radius direction (r). In addition, the radius blades 200 may be spaced apart in the circumferential direction (θ).

Each of the radial blades 200 may include one end 202 provided at an upper portion and the other end 204 spaced from the one end 202 in the rotational axis direction (z). For example, one end 202 of each radius blade 200 supports and is connected to the upper cover 400, while the other end 204 of each radius blade 200 may be connected to the lower cover 500.

The first circumferential vane 300 may be disposed between the inner circumferential vane 210 and the outer circumferential vane 220. Specifically, the first circumferential vane 300 may be disposed between the second circumferential vane 310 and the outer inner circumferential vane 210.

In addition, the first circumferential blade 300 may be elongated in the circumferential direction (θ). The first circumferential blade 300 may be connected to one end 202 of each radial blade 200 at the same time and may have a shape extending in the rotation axis direction (z), but may not be connected to the other end 204 of each radial blade 200.

The second circumferential vane 310 may be disposed between the first circumferential vane 300 and the outer circumferential vane 220. Specifically, the second circumferential vane 310 may be disposed between the first circumferential vane 300 and the third circumferential vane 320.

In addition, the second circumferential vane 310 may be elongated in the circumferential direction (θ). Additionally, a second circumferential vane 310 may be simultaneously connected to the other end 204 of each radial vane 200. The second circumferential blade 310 has a shape extending in the direction opposite to the rotation axis direction (z), but may not be connected to the one end 202 of each radial blade 200.

The third circumferential vane 320 may be disposed between the second circumferential vane 310 and the outer circumferential vane 220. Specifically, the third circumferential vane 320 may be disposed between the second circumferential vane 310 and the fourth circumferential vane 320.

Additionally, a third circumferential vane 320 is elongated in the circumferential direction (θ) to surround the second circumferential vane 310 and may be simultaneously connected to one end 202 of each radial vane 200. The third circumferential blade 320 may have a shape elongated in the rotation axis direction (z), but may not be connected to the other end 204 of each radial blade 200.

The fourth circumferential vane 330 may be disposed between the third circumferential vane 320 and the outer circumferential vane 220. In addition, the fourth circumferential vane 330 may be elongated in the circumferential direction (θ) to surround the third circumferential vane 320.

The fourth circumferential blade 330 may be connected to the other end 204 of each radial blade 200 at the same time and may have a shape extending in the opposite direction to the rotation axis direction (z), but may not be connected to the one end 202 of each radial blade 200.

The upper cover 400 may cover a space between the first circumferential vane 300 and the outer circumferential vane 220. Specifically, the upper cover 400 is connected to one end 202 of each radial vane 200, and has a shape extending in the circumferential direction (θ) to cover between the first circumferential vane 300 and the outer circumferential vane 220.

In addition, the upper cover 400 exposes a space between the first circumferential vane 300 and the inner circumferential vane 210 to form a suction hole 410 through which air for generating an air curtain is sucked. The suction hole 410 may have a shape that surrounds the inner circumferential vane 210 and is elongated in a circumferential direction (θ).

As shown in fig. 2, the first to fourth

circumferential caps

300, 310, 320, 330 may be all coupled to the lower cap 500 and assembled with the upper cap 400.

On the contrary, as shown in fig. 3, the upper cover 400 is coupled to the first circumferential blade 300 and the third circumferential blade 320, and the lower cover 500 is coupled to the second circumferential blade 310 and the fourth circumferential blade 330, so that the upper cover 400 and the lower cover 500 are assembled.

Accordingly, each radius blade 200 may include a first radius blade 206 coupled to the upper cover 400 and including one end 202 and a second radius blade 208 coupled to the lower cover 500 and including the other end 204.

Specifically, each radial blade 200 may have a first radial blade 206 and a second radial blade 208 connected thereto.

As shown in fig. 5 and 6, the lower cover 500 may have a shape spaced apart from the upper cover 400 in the rotation axis direction (z) and extended in the circumferential direction (θ) to cover a space between the inner circumferential blade 210 and the fourth circumferential blade 330. For example, the lower cap 500 may be coupled to both of the other ends 204 of each of the radius blades 200.

The lower cover 500 exposes the space between the fourth circumferential vane 330 and the outer circumferential vane 220 to form a discharge hole 510 for discharging the above-described air for generating an air curtain. The discharge hole 510 may have a shape that surrounds the fourth circumferential vane 330 and is elongated in the circumferential direction (θ). The discharge hole 510 may be divided by the first auxiliary radius blade 340, which will be described later.

The first auxiliary radius blades 340 may each connect the fourth circumferential blade 330 and the outer circumferential blade 220. Each first auxiliary radius vane 340 may be elongated in the radial direction (r). In addition, the first auxiliary radius blades 340 may be spaced apart in the circumferential direction (θ).

As shown in fig. 8, the first auxiliary radius blade 340 may be extended substantially in parallel in the rotational axis direction (z). Therefore, each first auxiliary radius blade 340 may be extended substantially in parallel with each radial sidewall in the rotational axis direction (z).

In exemplary embodiments, the first auxiliary radius blades 340 may be equally spaced apart in the circumferential direction (θ). In addition, the radial blades 200 may be equally spaced in the circumferential direction (θ).

In addition, the first to fourth

circumferential blades

300, 310, 320, 330 may be spaced apart from each other at equal intervals in the circumferential direction (θ) within the inner circumferential blade 210 and the outer circumferential blade 220.

Next, the operation principle of the cyclone ventilation apparatus shown in fig. 1 to 6 and 8 will be mainly described.

As shown in fig. 7, the cyclone ventilation apparatus 10 of the exemplary embodiment may include a rotating fan 100 and the above-described air conditioning fan. Therefore, air flows in through the suction hole 410 provided between the inner circumferential vane 210 and the first circumferential vane 300.

The air flowing into the suction hole 410 passes through the first to fourth

circumferential vanes

300, 310, 320 and 330 in a zigzag shape, and then is discharged through the discharge hole 510 provided between the outer circumferential vane 220 and the fourth circumferential vane 340. The air discharged from the discharge hole 510 may form an air curtain (B) around the above-mentioned foreign substances.

In a state where the air curtain (B) surrounding the foreign matter is formed, the cyclone fan 100 generates a cyclone (vortex) (C) to strongly suck the foreign matter into the inner circumferential blades 210.

The cyclone ventilating device 10 according to the exemplary embodiment may include the rotary rotating fan 100 and the above air conditioning fan that rotates. In particular, the air conditioner includes an inner circumferential blade 210 and an outer circumferential blade extending in a circumferential direction (θ), first to fourth

circumferential blades

300, 310, 320, 330 extending in the circumferential direction (θ) and accommodated in the inner circumferential blade 210 and the outer circumferential blade 220, and a radius fan 200 and a first auxiliary radius blade 340 extending in a radius direction (r).

Accordingly, the cyclone ventilation apparatus 10 of the exemplary embodiment can concentrate the external air flow inside by generating the difference in the internal and external air pressures. Specifically, a circular air curtain (B) may be formed by forming a cyclone (C) inside by the cyclone fan 100 and controlling the flow of the wind speed by the air conditioning fan.

The cyclone fan 100 may form a cyclone (C) that may suck the foreign matters generated from the pollution source, and the air conditioner fan may form an air curtain (B) surrounding the pollution source, thereby increasing suction and exhaust concentration of the cyclone fan 100 to the foreign matters and improving exhaust efficiency.

Fig. 9 is an exploded perspective view of a cyclone air interchanger of an exemplary embodiment. Fig. 10 is a plan view of the cyclone ventilation apparatus of fig. 9. Fig. 11 is a sectional view taken along line b-b' of fig. 10.

The cyclone ventilation apparatuses shown in fig. 9 to 11 have substantially the same or similar configurations and/or structures, except that the plurality of second auxiliary radius blades are removed from the cyclone ventilation apparatuses shown in fig. 1 to 8.

The air conditioner fan may include an inner circumferential vane 210, an outer circumferential vane 220, a plurality of radius vanes 200, a first circumferential vane 300, a second circumferential vane 310, a third circumferential vane 320, a fourth circumferential vane 330, a plurality of second auxiliary radius vanes 342, an upper cover 400, and a lower cover 500.

The second auxiliary radius blades 342 may each connect the fourth circumferential blade 330 and the outer circumferential blade 220. Each second auxiliary radius blade 342 may be elongated in the radial direction (r). In addition, the second auxiliary radius blades 342 may be spaced apart in the circumferential direction (θ).

As shown in fig. 11, the second auxiliary radius blades 342 may be elongated in a direction at an acute angle with respect to the rotational axis direction (z). Thus, each second auxiliary radius vane 342 may extend at a different angle from each radial sidewall 200. On the contrary, each of the radius blades 200 may be elongated in a direction forming an acute angle with respect to the rotational axis direction (z) like the second auxiliary radius 342.

The cyclone ventilating device 12 according to the exemplary embodiment may include the rotary rotating fan 100 and the above air conditioning fan that rotates. In particular, the air conditioner includes an inner circumferential blade 210 and an outer circumferential blade extending in a circumferential direction (θ), first to fourth

circumferential blades

300, 310, 320, 330 extending in the circumferential direction (θ) and accommodated in the inner circumferential blade 210 and the outer circumferential blade 220, and a radius fan 200 and a second auxiliary radius blade 342 extending in a radius direction (r).

In particular, each of the second auxiliary radius blades 342 is inclined in a direction having an acute angle with the rotation axis direction (z), thereby having an advantage of effectively forming an air curtain using air discharged from the discharge holes 510.

Fig. 12 is an exploded perspective view of a cyclone air interchanger of an exemplary embodiment. Fig. 13 is a plan view of the cyclone ventilation apparatus of fig. 12. Fig. 14 is a sectional view taken along line c-c' of fig. 13.

The cyclone ventilation apparatuses shown in fig. 9 to 14 have substantially the same or similar configurations and/or structures, except that the third and fourth circumferential vanes are omitted from the cyclone ventilation apparatuses shown in fig. 1 to 8. Therefore, the repetitive structure will not be described in detail.

The air conditioner fan may include an inner circumferential vane 210, an outer circumferential vane 222, a plurality of radius vanes 201, a first circumferential vane 300, a second circumferential vane 310, a plurality of third auxiliary radius vanes 344, an upper cover 402, and a lower cover 502.

The outer circumferential vanes 222 may be spaced apart from the inner circumferential vanes 210 in the radial direction (r). The outer circumferential blade 222 may be elongated in the circumferential direction (θ) and may have a hollow cylindrical shape.

The outer circumferential blade 222 includes first and second

circumferential blades

300 and 310 and a third auxiliary radius blade 344, which will be described later, and forms the appearance of the air conditioner fan.

The radius blades 201 may each connect an inner circumferential blade 210 and an outer circumferential blade 222. Each of the radius blades 201 may be elongated in the radius direction (r). In addition, the radius blades 200 may be spaced apart in the circumferential direction (θ).

Each of the radial blades 201 may include one end 203 provided at an upper portion and the other end 205 spaced apart from the one end 203 in the rotation axis direction (z). For example, one end 203 of each radial vane 201 supports and is connected to upper cap 402, while the other end 205 of each radial vane 201 may be connected to lower cap 502.

The upper cover 402 may cover the space between the first circumferential vane 300 and the outer circumferential vane 222. Specifically, the upper cover 402 is connected to the one end 203 of each radial blade 201, and has a shape extending in the circumferential direction (θ) so as to cover between the first circumferential blade 300 and the outer circumferential blade 222.

The lower cover 502 may have a shape spaced apart from the upper cover 402 in the rotational axis direction (z) and elongated in the circumferential direction (θ) to cover a space between the inner circumferential blade 210 and the second circumferential blade 310. For example, the lower cap 502 may be connected to both ends 205 of each radius blade 201.

The lower cover 502 exposes the space between the second circumferential vane 310 and the outer circumferential vane 222 to form a discharge hole 512 for discharging the above-described air for generating an air curtain. The discharge hole 512 may have a shape that surrounds the second circumferential vane 310 and is elongated in the circumferential direction (θ). The discharge holes 512 may be divided by a third auxiliary radius blade 344 to be described later.

The third auxiliary radius blades 344 may each connect the second circumferential blade 310 and the outer circumferential blade 222. Each third auxiliary radius blade 344 may be elongated in the radial direction (r). In addition, the third auxiliary radius blades 344 may be spaced apart in the circumferential direction (θ).

The cyclone ventilating device 14 according to an exemplary embodiment may include a rotary rotating fan 100 and the above air conditioning fan that rotates. In particular, the air conditioner includes an inner circumferential blade 210 and an outer circumferential blade extending in a circumferential direction (θ), first to second

circumferential blades

Thus, the cyclone ventilation device 14 of the exemplary embodiment can concentrate the external air flow inside by generating a difference in the internal and external air pressures. Specifically, a circular air curtain can be formed by forming a cyclone inside by the cyclone fan 100 and controlling the flow of the wind speed by the air conditioning fan.

The cyclone fan 100 may form a cyclone into which the foreign matters generated from the pollution source may be sucked, and the air conditioner fan may form an air curtain around the pollution source, so that suction force and exhaust concentration force of the cyclone fan 100 to the foreign matters may be increased, and exhaust efficiency may be improved.

In particular, since the air curtain may be formed using the first and second

circumferential blades

300 and 310, the cyclone ventilation apparatus 14 of the exemplary embodiment may have a compact structure and may have an effective exhaust performance in a narrow space.

The above-described embodiments are merely illustrative and not restrictive, and it should be understood by those skilled in the art that the present invention may be modified, changed or substituted by equivalents without departing from the spirit and scope of the present invention, which shall be covered by the claims.
