The operation of the present invention configured as described above will be described.

The state in which the first embodiment according to the present invention is first installed is the same as the solid line in FIG. 2.

In other words, the second filter 50 may be a state in which the second filter 50 is completely accommodated inside the main body 10 while being supported by the rail 13 without being exposed to the outside from the inside of the opening 12.

In this state, a flow path is formed between the upper side of the filter 20 and the lower side of the second filter 50, so that odors and vapors are sucked and exhausted as in a general range hood.

For example, in a state in which the second filter 50 is accommodated inside the main body 10, as shown in a of FIG. 3, odor and steam generated during the cooking of the food may be absorbed and exhausted.

Suction paths of the odor and steam are partially sucked and exhausted through the flow path formed between the filter 20 and the second filter 50, and the rest flows into the second filter 50 and then flows behind the flow path. It can be sucked and exhausted through 52.

On the other hand, in the above state, for example, if there are a lot of odor and vapor to be sucked and exhausted, the amount of inhalation should be increased. In this case, as shown in the virtual line of FIG. Use to increase.

At this time, some of the odor and steam is introduced through the filter 20 fixed below the main body 10 and then exhausted, and some of the remaining odor and steam are disposed below the exposed second filter 50. It flows in through the member 51 and is exhausted along the flow path 52.

As described in the second embodiment of the present invention, the operation of absorbing and releasing odor using a separate driving means is as follows.

The state before the operation of the first embodiment is the same as the solid line of FIG. 5.

That is, in this state, the second filter 50 connected to the transfer pipe 64 may be completely stored inside the main body 10, and may not be exposed to the outside of the opening 12.

In the first state as described above, for example, when the second filter 50 is not operated, the odor and steam introduced through the filter 20, as in the first embodiment, are the same as described in the first embodiment. Intake and exhaust are through the same route.

However, when the switch 11 is operated to use the second filter 50, the drive motor 61 is driven by receiving the signal of the switch 11 to rotate the shaft 63.

As described above, when the shaft 63 is rotated, the rotational force of the shaft 63 is transmitted to the transfer pipe 64 so that the transfer pipe 64 moves in a straight line. As a result, the second filter 50 moves out of the opening 12. Exposed to maintain the same state as the virtual line in the drawing.

As described above, the operation of sucking and exhausting the odor and the vapor in the state in which the second filter 50 protrudes to the outside is the same as described above, and thus the description thereof will not be repeated.

However, when the withdrawal operation of the second filter 50 is described in detail, when the driving motor 61 rotates to transfer the second filter 50, the sensing unit 65 detects the rotation speed and the rotation speed is set. For example, when the speed exceeds 60 rpm, the detected number of revolutions is transmitted to the detection sensor 66, and the detection sensor 66 receives the signal from the received detection unit 65 and delivers the signal to the switch 11 to drive the drive. The driving motor 61 is stopped by cutting off the power supplied to the motor 61.

Accordingly, the stopper 67 of the second filter 50 is maintained by the series of operations as described above, or the stopper 67 provided in the second filter 50 to be touched touches the second switch 69 to drive the motor. By stopping the driving of the 61, the withdrawal state of the second filter 50 can be maintained.

Of course, when the second filter 50 is returned to its original state, the switch 11 is operated again to reverse the driving motor 61, and accordingly, the second filter 50 is advanced in the reverse direction. As described above, the sensing unit 65 detects the rotation speed and transmits the rotation speed to the detection sensor 66 when the set rotation speed is reached, and the detection sensor 66 is operated by the above-described operation. The drive of the drive motor 61 is stopped.

In addition, the stopper 67 operates the first switch 68 and the first switch 68 transmits the signal to the switch 11 to stop the driving of the driving motor 61 as described above. do.

On the other hand, as shown in Figure 7 the structure of the drive means 60 of the drive gear 61-1 provided on the shaft of the drive motor 61 and the rack 61-2 meshed with the drive gear 61-1 If the structure is also the same as the embodiment of the driving means described above, a separate description thereof will be omitted.

Of course, the rollers installed on both sides of the second filter will slide smoothly between the rails during the series of operations in which the second filter enters and exits by the operations of the first and second embodiments.

And the structure of the drive gear 61-1 provided in the shaft of the drive motor 61 of the drive means 60 and the rack 61-2 which meshed with the drive gear 61-1 is installed in the substantially center of a main body. Although limited to this, the present invention is not limited thereto, and the power may be transmitted in a state where it is installed on one side of the second filter.

On the other hand, the operation of the third embodiment of the present invention is similar to the operation of the first and second embodiments described above.

That is, when the drive motor 61 rotates and the shaft 63 rotates, the tubular body 70 through which the shaft 63 penetrates is moved forward and backward by the rotational force of the shaft 63.

Therefore, the operation of entering and exiting the second filter 50 by the driving force of the driving motor 61, which is the object of the present invention, is almost the same, but the operation of the third embodiment is the simplest and the number of internal parts is effective. can do.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the embodiments described above are to be understood as illustrative and not restrictive in all aspects.

The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
