<P>PROBLEM TO BE SOLVED: To provide a ventilating device capable of efficiently ventilating evaporated matters such as oily smoke and odor generated in heating cooking not only at home but also indoors by lowering a suction pipe having a moving up-and-down function to prevent contamination of circumference of an indoor ceiling and a wall surface, being raised in no-use to keep harmony with the ceiling surface as an interior accessory, and further coping with a building having a shallow depth under a roof though it has the moving up-and-down function on its mounting face. <P>SOLUTION: This ventilating device is supported at a ceiling surface side, and formed by connecting a plurality of suction openings overlapped to each other in several stages, by a plurality of suspender ropes 4 from the ceiling surface at lower ends of the suction openings. The plurality of ropes 4 are simultaneously operated by rotating a take-up reel 3 mounted on an upper part of the device and having a plurality of grooves, and a moving up-and-down function is provided to noiselessly move up and down the suction openings of several stages, that is, suction pipes. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention relates to a ventilator having an elevating function attached to an indoor ceiling surface.

When heating indoors as well as ordinary households, the generated smoke, steam, etc. cannot be efficiently discharged to the outside, which may cause indoor odors and dirt due to ceilings, walls, curtains, furniture, etc. The invention to be solved is to solve the problem with a ventilator having a plurality of overlapping air inlets in a lower opening that can be raised and lowered from the ceiling surface of the room.

An object of the present invention is to provide a ventilator that can efficiently discharge oily smoke, steam and the like indoors for cooking by heating and that does not damage the space when stored.

According to a first aspect of the present invention, a plurality of overlapping air inlets supported on the ceiling surface side are connected by a plurality of suspension ropes from the ceiling surface at the lower end of the air inlet, and the ropes are a plurality of grooves in the upper part of the apparatus. A plurality of ropes are simultaneously operated by the rotation of a take-up reel, and has a function of raising and lowering a plurality of blowing ports, so-called blowing pipes, that can be gently raised and lowered.
The lifting function has a multi-ply take-up reel with a groove on the ceiling side that is slightly larger than the diameter of the rope, and the other end is fixed to the lower inlet through the pulley, and the take-up reel is connected to a motor, etc. If it is rotated as a power source, the blow pipe consisting of several steps from the ceiling side is kept in order and descends toward the heating cooking section and stops at a predetermined position to achieve the intended purpose.

According to the second aspect of the present invention, the blowing pipe has a U-shaped bent shape at the upper and lower portions of each blowing port, and the bending horizontal portion is provided with a packing to improve the adhesion of the contact surface of each blowing port. The sliding surface is provided with a roller on the inner side to provide smooth movement with no wobbling at the time of raising and lowering, and further, the roller rotates so that no damage is caused on the wall surface of the blowing port.

The third aspect of the present invention is characterized in that since the intake port can be stored close to the ceiling surface when it is raised, there is no heavy pressure in the room, and the interior appearance is high by applying a design such as a wood grain to the apparent appearance. Here, the design, for example, the woodgrain, can be painted without causing any harm to the indoor space.

Further, according to the fourth aspect of the present invention, the mesh portion of the design is further provided inside the lowermost end of the air inlet, and a filter that can be easily replaced when clogged is further provided. Here, when replacing the filter, the lowermost end of the air inlet can be lowered manually. The two-stage structure (link mechanism) makes it possible to work below the line of sight, and the filter can also be replaced with a single touch. Another feature is that the lower link mechanism serves the double safety of dropping parts with a rope and a mesh filter at the bottom end.

As described above, according to the present invention, (1) this apparatus for the purpose of accurately collecting transpiration such as oily smoke and odor generated during cooking in the room and helping to create an indoor environment is as described above. Can be realized by lowering to a predetermined position. In addition, the filter replacement when clogged has a two-stage structure at the bottom, so it is safe to work below the line of sight.
(2) Further, when it is not in use, it can be stored up and close to the ceiling surface, so that the feeling of heavy pressure in the room is eliminated, and the painting and the like are applied to the installation, so that the interior can be enhanced.

This will be described with reference to the drawings.
FIGS. 1 to 4 show an example of the present invention.

A suction pipe 9 having a drive mechanism / exhaust function at the lower part and having a plurality of stages is provided at the upper part with the ceiling finish height as a boundary.

The drive mechanism includes a drive motor 1, a drive pulley 2, a take-up reel 3, a rope 4, a support base 5, and a pulley 6.
The take-up reel 3 transmitted and rotated from the drive motor 1 has a deep groove shape as if a plurality of grooves were processed, and the rope 4 can be wound around each groove position without being twisted by being stacked several times. is there. The other end of the rope 5 of the take-up reel 3 is connected and fixed to the lowermost blowing port. The pulley 6 of the support base 5 on the road is fixed to the pulley 5 so that any part of the rope 4 is always horizontal. The level is set so that the deep groove portion of the take-up reel 3 is not worn.

For the exhaust function, a ventilator mounting hole is provided in the upper part of the ceiling, and the exhaust duct pipe leading to the intake port 8 uses the ceiling space. The smoke, odor, and other transpiration matter sucked from the lowermost suction port 12 passes through the suction pipe 9 that goes up and down, and is exhausted from the several intakes provided in the upper part of the ceiling to the exhaust duct pipe. It is exhausted from the mouth. At this time, depending on the location of the exhaust fan, install an exhaust fan suitable for this ventilation system.

The suction pipe 9 that moves up and down is composed of a suction port 12 that houses the design mesh 10 and the filter 11 at the lowest end.
Several suction pipes 9 have U-shaped bent shapes 9-1 above and below the respective suction pipes 9, and the suction pipes 9 are directed downward to gradually increase the inner dimensions and overlap several times. And configure the suction pipe.
The U-shaped bent portion 9-1 below each suction pipe 9 is provided with a roller 9-2 to prevent friction during sliding and smooth movement and swinging during ascent and descent. Does not cause scratches on the wall. Further, the horizontal portion of the U-shaped folding is provided with a packing 9-3 to enhance the close contact of each suction pipe 9 and maintain airtightness, and at the same time, the combination of the U-shaped folding portion 9-1 prevents the fall. Has been.
Further, the lowermost blowing port 7 has a two-stage structure that can be further lowered from the lower end position of normal use, and the replacement of the filter 11 stored in the lowermost blowing port when clogged is less than the line of sight. Moreover, the filter 11 has a function that can be exchanged with one touch.

  The figure at the time of storage (at the time of a raise) of this invention is shown.   Shows when in use (descent).   Shown when the filter is changed (further down).   The figure of the rope groove of the take-up reel is shown.
