Description

Ventilation device for stove hood {Ventilation system for use in range hood}

The present invention relates to a range hood ventilator, and more particularly, to reduce the diameter of the vent duct (duct) and use a duct with a smooth surface, thereby ensuring a wide field of view and improving the collection efficiency. Relates to a device.

In general, a stove hood is installed in a kitchen such as a home or a restaurant for cooking food, and smoke, smell, dust, etc. are generated from the food placed on the stove hood or the stove hood when cooking food. Therefore, an appropriate ventilation device is installed to discharge such smoke, odor, dust, and the like to the outside.

Ventilation system is divided into natural exhaust type which ventilates by the difference of atmospheric pressure inside and outside and forced exhaust type which is forcibly ventilated by blowing fan.

Figure 1 shows such a forced exhaust ventilation device. As shown, the ventilator is a corrugated pipe-shaped duct (1) installed downward from the ceiling (3) to be the discharge passage of the smoke, and a blowing fan installed in the upper end of the duct (1) to generate a suction force by rotating It includes (2).

The ventilator having this structure rotates the blowing fan 2 to discharge the smoke generated from the stove hood 4 to the outside. When the blowing fan 2 rotates, suction force is generated, so smoke is introduced into the duct 1 and discharged to the outside through the discharge port 5. At this time, the diameter D of the said duct 1 is 6 cm or more normally.

By the way. Such a ventilation device has a problem that the discharge efficiency is lowered due to friction with the inner wall surface when the smoke flows through the duct has a corrugated pipe shape.

Since the discharge efficiency is reduced to compensate for the reduced efficiency by expanding the diameter of the duct, there is a problem that covers the user's field of view by expanding the diameter of the duct. In particular, large restaurants where a large number of ducts are provided have a tendency for the indoor atmosphere to be poor due to a narrower field of view.

In addition, since a large-capacity blowing fan is used to increase the discharge efficiency due to the use of the corrugated pipe, there is a problem that the noise increases and the blowing fan takes up a lot of space.

In addition, since the range hood and the duct are spaced apart from each other, the smoke generated from the range hood diffuses in all directions before being sucked into the duct, thereby making it difficult to effectively inhale the smoke.

Accordingly, an object of the present invention is to provide a ventilation hood ventilation apparatus that can improve the exhaust efficiency by reducing the air resistance by reducing the air resistance by using a slot-type duct smooth surface to solve the above problems.

In addition, by providing a close duct close to the stove hood to provide a ventilator that can suck the smoke generated from the stove before it spreads in all directions to increase the discharge efficiency.

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

Figure 2 is a perspective view showing a vent hood ventilation apparatus according to the present invention, Figure 3 is a side cross-sectional view of the vent hood ventilation apparatus shown in FIG.

As shown in the drawings, the vent hood ventilation apparatus proposed by the present invention includes an air moving means 10 which becomes a passage through which smoke flows, a hinge member 17 which supports the air moving means 10 to be hinged, It is mounted on top of the air moving means 10 includes a blowing fan 14 for generating a suction force to suck the smoke.

The air moving means 10 (hereinafter, duct) is composed of a plurality of small diameter pipes (11, 12, 13) having a different diameter (D1), can be folded by a telescopic method (Telescopic).

That is, the plurality of small diameter pipes (11, 12, 13) is folded in a telescopic manner by assembling a plurality of pipes in a manner in which a smaller diameter tube is assembled inside the larger diameter tube. Thus, the duct 10 is contracted or stretched if necessary.

In addition, the plurality of small-diameter pipes (11, 12, 13) includes a slot-type pipe (Slot-type pipe) that the inner surface is formed smoothly. The slot-type tube is formed with a smooth inner surface when air flows therein, thereby reducing fluid resistance. Therefore, the fluid resistance is reduced compared to the case of using a corrugated pipe, the air discharge efficiency is high. As a result, even if the capacity of the blower fan 14 is reduced, the same discharge efficiency as that of the corrugated pipe is achieved.

In addition, the plurality of small diameter pipes (11, 12, 13) has a small diameter (D1), preferably has a diameter (D1) in the range of 6 cm or less. Even if the diameter (D1) as described above, because the use of a slot-type pipe smooth surface compared to the corrugated pipe can maintain the same level of discharge efficiency.

As a result, since the diameter D1 of the duct 10 is made small, the field of view can be secured widely, and the field of view is secured at a place where a vent hood for each hood is installed in each table, such as a restaurant.

On the other hand, in order to shrink and extend the duct 10 in a telescopic manner, the duct 10 is equipped with a folding driving means 30 (Fig. 4). This folding drive means 30 (Fig. 4), as shown in Figures 4 to 6, several embodiments are disclosed.

4 illustrates a method of contracting / extending the duct by an iron piece having an appropriate elastic force as a preferred embodiment of the folding driving means.

That is, one end 21a of the iron piece 21 is wound around the rotating shaft 23 of the motor assembly 22 mounted inside the ceiling 16, and the other end 21b is provided with a plurality of small diameter pipes 11, 12, 13 is passed through the inside of the small-diameter tube 13 at the lowermost end is connected by a method such as welding, gluing, bolts. Therefore, when the iron piece 21 is wound around the motor assembly 22, since the iron piece 21 pulls the small-diameter tube 13 at the lowermost portion, the plurality of small-diameter tubes 11, 12, 13 are Since it contracts sequentially, the length of the duct 10 is eventually contracted.

On the contrary, when the rotating shaft 23 of the motor assembly 22 is rotated in the reverse direction and the iron piece 21 is released from the rotating shaft 23 of the motor assembly 22, the small piece diameter tube of the lowermost end ( Since the 13) is pushed downward, the plurality of small diameter pipes (11, 12, 13) is elongated in sequence so that the length of the duct (10) is increased.

At this time, the iron piece 21 has a predetermined elastic force and has sufficient strength to push the plurality of small diameter pipes (11, 12, 13) downward.

Thus, the user can arbitrarily adjust the length of the duct 10 to the desired degree by controlling the driving of the motor assembly 22. In addition, the iron piece 21 may be replaced with a general wire without elasticity. That is, when the duct 10 is extended downward, it is possible to extend downward by the weight of the plurality of small diameter pipes 11, 12, 13, and when the wire is contracted, the wire is wound around the rotating shaft of the motor assembly 22. By shrinking.

In addition, the method of controlling the motor assembly 22 may be various methods such as a method by an on / off switch (not shown) and a remote control method.

As another embodiment of the folding driving means 30, it is also possible to mount the iron piece 31 on the outside of the duct 10, as shown in FIG. That is, it has the same structure as the embodiment shown in FIG. 4, but the motor assembly 34 is mounted on the bottom of the ceiling 16, and the iron piece 31 is mounted on the outside of the duct 10. This embodiment is applicable when the discharge piece due to friction with the air is reduced because the iron piece 31 shown in FIG. 4 is located inside the duct 10.

A plurality of supports 32 are attached to the outer circumferential surface of the duct 10 spaced apart from each other by a predetermined interval. In addition, guide holes 33 are formed in the plurality of supports 32, and the iron pieces 31 are supported by penetrating the guide holes 33.

Therefore, the iron piece 31 is wound or unwound by forward / reverse rotation of the rotating shaft 35 of the motor assembly 34, thereby contracting / extending the duct 10.

Even in this case, the iron piece 31 can be replaced with a general wire without elasticity.

Another embodiment of the folding drive means 30 (FIG. 4) is shown in FIG. 6. As shown, each of the plurality of small diameter tube (11, 12, 13; Fig. 3) is formed with a pair of projections 52 protruding on both sides on the outer upper edge of the outer, respectively, a predetermined depth on the inner surface A pair of guide grooves 55 are formed. The pair of guide grooves 55 are formed spirally along the length of the small diameter tube.

In the case of assembling a plurality of small-diameter tubes 11, 12, 13 (FIG. 3) having such a shape, a pair of projections 52 of one small-diameter tube 51 is a pair of other small-diameter tubes 53. Insert into the guide groove (54).

Then, when one small diameter tube 51 is rotated in the other small diameter tube 53 in the inserted state, the one small diameter tube 51 moves upward.

In this way, the plurality of small diameter pipes 11, 12, 13 (FIG. 3) are assembled to each other and rotated clockwise and counterclockwise to contract and extend the duct 10 as necessary.

On the other hand, as shown in Figure 3, the duct 10 is hingedly attached to the ceiling 16 by the hinge member 17 can be fixed by maintaining a predetermined angle. That is, the user may use the fixed duct 10 in a desired position by pushing or pulling the duct 10 to one side.

One embodiment of such a hinge member 17 is shown in FIG. 7. As shown, the hinge member 17 has a spherical support bracket 18 attached to the ceiling 16, and a spherical and rotatable insertion hole rotatably mounted inside the support bracket 18. As shown in FIG. (19).

Since the rotation insert 19 is in close contact with the inside of the support bracket 18, the rotation insert 19 can maintain the angle even in a state inclined to one side.

The rotation insertion hole 19 is integrally formed on the upper portion of the small diameter tube 11 is located at the top of the plurality of small diameter tube (11, 12, 13; Fig. 3). As a result, since the duct 10 is fixed to the ceiling 16 by the hinge member 17, it is possible to push or pull the duct 10 to one side. Therefore, even when the position of the range hood 15 (FIG. 3) changes, it is convenient to use by moving the duct 10 to the changed position.

Another embodiment of the hinge member 17 is shown in FIG. 8. As shown, the bearing 62 is additionally mounted to the hinge member 17 shown in FIG. 7 to further prevent the rotation insertion hole 19 from sliding inside the support bracket 18.

That is, the first half groove 61 is symmetrically formed at a predetermined position on the inner circumferential surface of the support bracket 18, and a plurality of second half grooves 63 are formed on the outer circumferential surface of the rotation insertion hole 19. In addition, the bearing 62 is mounted in an inner space formed between the first half groove 61 and one half groove of the plurality of second half grooves 63.

Accordingly, when the rotation insertion hole 19 is pulled or flipped in the direction of the arrow, the rotation of the bearing 62 of the first half groove 61 is sequentially caught or disengaged from the plurality of second half grooves 63. Insertion port 19 is rotated. When the rotation insertion hole 19 stops at an angle, the bearing 62 is caught by one half groove of the plurality of second half grooves 63. Therefore, the duct 10 can be fixed by maintaining a predetermined angle.

Meanwhile, as shown in FIG. 3, the conical dust collecting plate 40 is integrally mounted at the lower end of the duct 10, and the diameter of the dust collecting plate 40 is small. Even if the diameter of the dust collecting plate 40 is small, the suction efficiency is greater than that of the large dust collecting plate 40.

That is, by extending the duct 10 by a telescopic method, the dust collecting plate 40 is moved to a position near the range hood 15. Therefore, the smoke generated from the range hood 15 is sucked into the dust collecting plate 40 before spreading in all directions, so that the suction efficiency is improved even with a small diameter.

The dust collecting plate 40 is made of a material having a low thermal conductivity, and a dust collecting member 41 is mounted therein to remove impurities such as oil contained in smoke. In addition, the dust collecting member 41 may be selectively applied to an inertial force type, a filtration filter type, an adsorption type, an electric type, and the like.

Of course, the hood hood ventilator having the structure described above can be applied to other purposes, preferably for indoor ventilation.

Hereinafter, with reference to the accompanying drawings will be described in more detail the operation process of the vent hood ventilator according to a preferred embodiment of the present invention.

2 to 8, the duct 10 attached to the ceiling 16 is pulled down to a position adjacent to the hood hood 15 in order to discharge the smoke generated from the hood hood 15 to the outside. First, the user drives the motor assembly 22 by using a switch (not shown), and the iron piece 21 is released from the motor assembly 22 by driving the motor assembly 22.

Therefore, the duct 10 is extended by pushing the lower end part of the small piece diameter pipe 13 of the lower end part downward. At this time, the dust collecting plate 40 of the duct 10 is moved to a position close to the stove hood 15, it can be sucked before the smoke is spread in all directions.

When the duct 10 is extended, a switch (not shown) is operated to rotate the blower fan 14. As the blowing fan 14 rotates, suction force is generated in the duct 10, and smoke generated from the range hood 15 is introduced into the duct 10. Smoke introduced into the duct 10 is discharged to the outside through the exhaust port 20 through the blowing fan 14. At this time, since the diameter D1 of the duct 10 is small, the user can secure a wide field of view.

After use, when returning the duct 10 to its original position, the motor assembly 22 is driven by operating a switch (not shown). As the motor assembly 22 is driven, the iron piece 21 is wound around the rotation shaft 23 of the motor assembly 22, so that the duct 10 is contracted by a telescopic method. Thus, the duct 10 is located on the ceiling 16, the interior space is neatly tidy.

When moving the range hood 15 to another place, the user can also move the duct 10 to the moved place by pushing left and right or clockwise and counterclockwise.

That is, when the duct 10 is pushed or pulled in a predetermined direction, the rotary insertion hole 19 rotates inside the support bracket 18 attached to the ceiling 16. At this time, since the rotation insertion hole 19 is coupled to the inside of the support bracket 18 in close contact, the duct 10 may be stopped while maintaining a predetermined angle. Thus, the user can position and use the duct 10 at a desired angle.

As described above, the range hood ventilator according to the present invention has the following advantages.

First, the ventilator for the ventilator has the advantage of ensuring a wide field of view at places such as restaurants by using a small diameter pipe. At this time, the duct can maintain the same discharge efficiency as the duct having a large diameter by reducing the fluid friction with the inner wall surface of the pipe during the distribution of smoke by using a slot-type pipe smooth surface.

Second, even when using a small diameter pipe maintains the same discharge efficiency as the case of using a large diameter pipe has the advantage of reducing the size of the blowing fan. Therefore, the noise due to the rotation of the blowing fan can also be reduced.

Third, since the duct can be telescopically extended and moved to the position near the range hood, the smoke generated from the range hood is sucked into the dust collecting plate before spreading in all directions, so the suction efficiency of the small diameter dust collecting plate can be increased. have.

Fourth, since the duct of the ventilation device is mounted to the ceiling by the hinge member, it can be maintained at a predetermined angle by pushing to one side. Therefore, there is an advantage that cooking can be performed by placing the duct in a new stove hood installation place even when the position of the stove hood is changed.

Fifth, since the duct is composed of a plurality of small diameter tube can be folded in a deletic method, there is an advantage that can be maintained in a tidy atmosphere by folding and placing on the ceiling when not in use.

The present invention can be variously modified by those skilled in the art to which the present invention pertains without departing from the scope of the present invention as claimed in the claims, and is not limited to the specific preferred embodiments described above. .
