Abstract

PURPOSE:To provide a ventilating device capable of opening and closing a movable hood without staining hands by providing a spring for outwardly opening the movable hood provided at a suction port, a damper for actuating the movement of the movable hood, and a locking mechanism for holding the movable hood in a closed state. CONSTITUTION:When cooking is started using an over 11, a switch 25 is pushed to rotate an exhaust fan 14 to carry out the exhaustion of smoke and vapor generated by the oven 11. When a large quantity of smoke and vapor are generated, the front surface of a movable hood 15 is pushed, and then a locking mechanism 23 is released. Thus, the movable hood 15 is slowly opened, and positive exhaustion is carried out. When cooking is completed and the front surface of the movable hood 15 is pushed against a force exerted by a spring, the movable hood 15 is locked in a state when the movable hood 15 is closed by a locking mechanism 23. When a switch 25 is depressed, the rotation of the exhaust fan 14 is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ventilation system that exhausts oily smoke generated during cooking to the outdoors using an exhaust fan.

BACKGROUND OF THE INVENTION Conventionally, this type of ventilation system has had a configuration as shown in FIG. An air intake port 2 is formed by opening the bottom surface of the box-shaped body 1, and an exhaust fan 3 is provided by opening the back surface or the top surface. The front part serves as a movable hood 4, which is pulled forward when exhausting smoke and stowed away when not in use. And in each state,
The notch 7 provided in the side plates 6, 6 of the movable hood 4 is
It is configured to fit into and be fixed to a horizontal bar 9 biased by a spring 8.

Problems to be Solved by the Invention In such a conventional configuration, when exhausting smoke, oily smoke is exhausted through the inner surface of the box-shaped body 1, and naturally the inner surface of the movable hood 4, so that oil adheres to them. There was a problem in that when holding the lower part of the movable hood 4 and pulling it out, oil would adhere to the hands.

The present invention solves these problems, and aims to provide a ventilation system that allows a movable hood to be opened and closed without getting one's hands dirty.

Solve problems. Means for Solving This Problem In order to solve this problem, the present invention has an exhaust fan inside the main body, and a spring for opening the movable hood provided at the intake port of the main body to the outside and a spring for moving the movable hood. It is equipped with a damper that moves the movable hood and a locking mechanism that holds the movable hood in a closed state.

Function: This configuration allows the movable hood to be opened and closed by operating the front surface of the movable hood without touching the oil attached to the inside of the movable hood.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3. In FIGS. 1 and 2, 1° is a ventilation device installed at a certain distance above the stove 11 in FIG. Exhaust fan 1 is formed by opening the back or top surface.
4 are provided. The front part is covered with a movable hood 16 whose upper part is rotatably supported, and a spring 1e.
It is always biased in the open direction. Reference numeral 17 denotes a damper for decelerating the movement of the movable hood 16. As shown in FIG.
It is meshed with a gear 22 provided in the. Numeral 23 is a locking mechanism, which locks a protrusion 24 provided on the side plate 21 with a magnet, and is unlocked when the front surface of the movable hood 15 is pushed again. 25 is a switch for rotating and stopping the exhaust fan 14.

The operation in the above configuration will be explained. First, when starting cooking on the stove, when the switch 26 is pressed, the first exhaust fan 14 rotates to exhaust smoke and steam generated on the stove 11. When using the front stove to generate a large amount of smoke or steam, press the front of the movable hood 15 to release the locking mechanism 23 and allow the spring 16 and damper 17 to slowly open the movable hood 16. Make sure to exhaust the air. When cooking is finished, when the front surface of the movable hood 15 is pushed against the spring force, the movable hood 15 is locked in the closed state by the locking mechanism 23. Then, when the switch 25 is pressed, the rotation of the exhaust valve 14 is stopped. In this way, when the ventilation device 1o is not used, the movable hood 15 is closed and the room is in a clean state. Note that the damper 17 and the lock mechanism 23 are not limited to the systems described in this embodiment.

Effects of the Invention As described above, according to the present invention, the movable hood can be opened and closed simply by pressing the front surface of the movable hood, so the hands do not touch the inner surface of the movable hood and the hands do not get dirty with oil. Also, the movable hood opens slowly using a spring and damper, so there is no chance of the movable hood accidentally hitting your head. In addition, even if the head hits the movable hood when it is open, the spring force causes the head to escape backwards, preventing any injuries.
