Accordingly, the main body 30 is movable in both the horizontal and vertical directions with respect to the wall surface and more specifically, the frame portion 10 as a reference, and thus the suction pipe 34 of the main body 30 is ) is also the position closest to the source of combustion gas and harmful gas, and it is possible to move both horizontally and vertically.

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

3 (a) and (b) are perspective views illustrating a state before and after horizontal movement of the range hood suction pipe according to the present invention.

As shown, according to a preferred embodiment of the present invention, one side is coupled to the frame portion 10, more specifically the horizontal frame 12, and the other side is the receiving portion 20, more specifically the upper rim. Since a plurality of main sliding rails 65 coupled to the face part 22 are provided, the receiving part 20 is moved horizontally by the main sliding rails 65 as shown in FIGS. 3(a) to 3(b). will move

In addition, when the accommodating part 20 is moved in the horizontal direction, the lower plate 462 is inserted into the ball bush 44 and coupled with the guide rod 42, so that it does not move in the horizontal direction, but the upper plate 464 ) and the lower plate 462 are slidably coupled to each other by the auxiliary sliding rail 75, and thus move in the horizontal direction as shown in 3(b) in FIG. 3(a).

That is, when the user grabs the handle and pulls it as described above, the accommodating part 20 can move in the horizontal direction, and as a result, as shown in FIG. The suction pipe 34 of the main body 30 inserted into the formed through-hole 26 is also movable in the horizontal direction.

4 (a) and (b) are perspective views illustrating a state before and after vertical movement of the range hood suction pipe according to the present invention.

The lifting means 40 of the range hood of the present invention interconnects the frame portion 10 and the body portion 30, and the housing portion 20 does not move in the vertical direction and the body portion 30 ) only to be able to ascend and descend.

That is, the elevating means 40 includes a guide rod 42 coupled to the frame portion 10 largely as described above in FIG. 2 , a ball bush 44 movably provided to the guide rod, and the ball A main plate 46 coupled to the bush 44 and connected to the main body 30, a main motor 48 coupled to one side of the main plate, and a wire 49 connecting the main motor and the upper side of the guide rod ) is included.

Since the lower plate 462 is inserted into the ball bush 44 and coupled with the guide rod 42, when the ball bush is moved in the vertical direction, the main plate ( 46) will also ascend and descend.

On the other hand, as shown, the main motor 48 is interconnected with the end of the fixing pin 422 provided on the upper side of the guide rod 42, more specifically, the bracket 424 by a wire 49. , when the main motor 48 is driven, the main plate 46 can be raised and lowered by a considerable length to the guide rod 42 through the wire 49 .

Conversely, when the main motor 48 is driven in the reverse direction, the wire 49 wound around the pulley connected to the drive shaft of the main motor 48 is unwound and the body portion 30 is moved by its own weight in FIG. 4(b). As shown in Fig. 4 (a), the bar moves to the lower side, and thus the maximum elevating distance in the vertical direction of the main body 30 is the guide according to the distance between the receiving unit 20 and the lower gas range or electric range. Of course, when the length of the rod 42 is varied, it is sufficiently variable.

According to the present invention as described above, only the suction pipe 34 from the main body 30 can variably protrude to the outside of the receiving unit 20, and as a result, the structure of the range hood is simplified and the effect of inducing the user's sensitivity is expected. do.

That is, when the range hood according to the present invention is not used, the inlet of the suction pipe 34 is blocked with the cover 342 as shown in FIG. As the screw 86 connected to the drive shaft rotates by the rotation of the auxiliary motor 85 as shown in FIG. 5(b), the nut part 90 of a certain length screw-coupled thereto descends, and as a result, the As the cover 342 descends, the inlet of the suction pipe 34 is opened.

Here, the auxiliary motor 85 is also driven by a separate external switch (not shown) or driven by receiving a signal from a user detection sensor (not shown) provided on one side of the range hood according to the present invention. Of course it could be.

Therefore, according to the present invention as described above, since the horizontal direction and further vertical movement are possible, the suction pipe can be moved closest to the combustion gas and harmful gas generating source.

In addition, the shape of the suction pipe also has a cross-sectional area from a circular shape to an elliptical shape to reduce the volume occupied by the suction pipe, so that even if the suction pipe descends and approaches the source, it is easy to secure a view of the cook.

Furthermore, the upper side of the suction pipe is rotatably coupled by a ring-shaped clamp, and the lower side of the suction pipe is rotatably coupled by a plug rotatably coupled to a through-hole formed in a circular shape, so that the crater has two to It is possible to efficiently inhale combustion gases and harmful gases even though there are various numbers and craters arranged vertically and horizontally, such as 4 spheres.

For example, if the crater is horizontally arranged with 2 spheres, the long axis of the suction pipe is rotated horizontally. If the crater is arranged vertically, the long axis of the suction pipe is rotated so that the crater is vertically. In the above case, if the long axis of the suction pipe is rotated toward the crater to be used, the suction radius can be much wider than when the shape of the suction pipe is simply circular.

According to the present invention as described above, there is provided a range hood that enables the suction pipe for sucking combustion gas and harmful gas to be moved horizontally and vertically while being able to rotate, so that it can move most closely to the source of combustion gas and harmful gas. It can be seen that what is to be provided is the technical idea of the present invention.
