Abstract

<P>PROBLEM TO BE SOLVED: To provide a table ventilating fan simple in device constitution and installed at a low cost without polluting indoor environment with oily smoke or the like from cooking even if used in any room regardless of an installation place. <P>SOLUTION: Almost all of oily smoke generated in indoor grill cooking is captured by forced ventilation directly above a generating source by driving a small propeller fan 3 on a conical hood 2 installed directly above the generating source, and polluted air is exhausted outdoor via a flexible hose 6 of bellows shape. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a mobile assembly ventilation device that forcibly exhausts oily smoke and the like generated when cooking a pottery dish indoors.

Conventional mobile ventilators use a fixed indoor ventilation fan or an intake device installed at the outlet of a flexible pipe in the exhaust passage, both of which are forcibly suctioned away from the source of oil smoke It is a structure to do.

  However, according to the above technique, since the intake device is installed at the discharge port away from the oil smoke generation source, a problem occurs in the suction force. Moreover, the installation place is limited in the indoor ventilation fan type. In both cases, the forced suction system at these outlets reduces the suction force due to the length of the exhaust pipe, making it difficult to completely capture the large amount of oily smoke generated during cooking of pottery, resulting in some indoors becoming contaminated. Is done.

In order to solve the problem, the first invention is characterized in that a small propeller fan motor 3 is attached to a smoke collecting hood 2 directly above an oil smoke generation source to completely supplement the oil smoke and discharge it outside the room. It is a type assembly ventilation device.
In addition, the second invention is designed such that the exhaust flexible pipe is attached to a vertically attachable / detachable mounting frame that can be attached to any window in order to exhaust air to the outside using a window at home.

  According to the first invention or the second invention, the indoor environment is not polluted by cooking oil or the like even if used indoors without being caught by the installation location. In addition, the apparatus configuration is simple and can be installed at low cost.

One embodiment of the present invention is shown in FIGS.
The generated oil smoke 1 is forcibly sucked by a small propeller fan motor 3 installed immediately above the exhaust port of the conical smoke collecting hood 2 and is discharged to the outside through the bellows type flexible pipe 6. Since the smoke collection hood is made of a heat-resistant resin material and the propeller fan motor is small and light, the assembly stand 4 that supports them is also composed of a combination of small-diameter metal pipes. Since the exhaust flexible pad also uses a thin-walled aluminum forming pipe, the entire device is reduced in weight and can be supported at two points: a window frame and an assembly stand.

Effects of the embodiment

  According to this embodiment, it is an apparatus that can be easily disassembled after use and does not take up space for storage.

Other embodiments

  In the embodiment of FIG. 3, the mounting frame for passing the exhaust pipe indoors and outdoors is designed to be extendable and retractable with a double structure of the outer frame and the inner frame, and can be attached to any window.

It is a side view which shows the movable assembly ventilation apparatus concerning this invention. It is a top view which shows a mobile assembly ventilation apparatus. It is a front view which shows a window mounting frame.

Claims (2)

Oil smoke generated when cooking grilled foods indoors is driven by a small floppler fan on a conical hood installed above the source, and forced intake is performed directly above the source to capture almost all generated oil smoke. An assembly-type ventilator that is not trapped by the installation site, and discharges polluted air to the outside via the bellows-shaped flexible hose. The bellows-shaped exhaust flexible hose is a ventilation device that allows the exhaust location to be freely selected by integrating it with a vertically extendable window mounting frame that can be mounted without being restricted by the size of the window.
