Title:
Gas stove deflecting air-wall structure
Kind Code:
A1


Abstract:
The invention discloses a gas stove deflecting air-wall structure including a jet airflow discharging device disposed near a gas stove consisted of a U-shaped tube from three individual tubes using universal joints. Within each of the tubes is provided with a squirrel cage, and adjacent tubes are connected by means of multi-directional swivels. One of the squirrel cages is connected with a motor that drives and rotates the squirrel cages, and the airflow generated within the tubes is discharged through outlets at the top thereof, thus forming a invisible and transparent air-wall. The air-wall formed then forwards smoke produced by a smoke exhaust upwards to the suction area of the smoke exhaust, thereby preventing the smoke dirtying kitchen utensils and harming the health as being inhaled by human lungs.

Description:

BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The invention relates to an invisible air-wall structure formed between a gas stove and a smoke exhaust by means of a jet airflow discharging device. The air-wall then separates the air in and out of the air-wall and forwards the smoke produced by the smoke exhaust upwards to the suction area of the smoke exhaust, thereby preventing the smoke from dirtying kitchen utensils and harming the health as being inhaled by human lungs.

[0003] (b) Description of the Related Art

[0004] A conventional gas stove is generally provided with a smoke exhaust above that discharges the smoke produced by the gas stove. A distance usually exists between the gas stove and the smoke exhaust, and thus forming dead corners unreachable by the smoke exhaust. And therefore part of the smoke produced yet dirties kitchen utensils or even affects the health as being inhaled by human lungs.

SUMMARY OF THE INVENTION

[0005] Therefore, an object of the invention is to provide a jet airflow discharging device for installing near a common gas stove. The jet airflow discharging device, through rotation of a three-segmental squirrel cage driven by a motor, is capable of separating the air in and out of an invisible air-wall formed upwards from the jet airflow produced, thus forwarding the smoke upwards to the suction area of the smoke exhaust. The suction deficiency of the smoke exhaust is then compensated for preventing the smoke from dirtying kitchen utensils and harming the health as being inhaled by human lungs.

[0006] Another object of the invention is to drive the smoke produced by directing the airflow upwards to the suction area of the smoke exhaust by disposing a deflecting air-wall capable of compensating the airflow deficiency at the two ends of the tube of the squirrel cage, respectively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Illustrations of the invention shall be given with the accompanying drawings hereunder.

[0013] Referring to FIG. 1, above a common kitchen gas stove 1 is provided with a smoke exhaust 2, whose blow discharges the smoke produced during cooking. The characteristics of the above shall be described below.

[0014] As shown in FIG. 2, near the gas stove 1 is disposed with a jet airflow discharging device 3 consisted of three tubes 31, 32 and 33, two universal joints 34 and 35, and a motor 36. Wherein, two adjacent tubes 31 and 32, 32 and 33, are connected to the universal joints 34 and 35 by means of screw bolts, respectively, to form a U-shaped tube. In the tubes 31, 32 and 33 are provided with squirrel cages 311, 321 and 331, respectively, as shown in FIG. 3. An axle of the motor 36 is connected to the squirrel cage 311 within the side tube 31, and the squirrel cage 311 within the side tube 31 is also connected to the squirrel cage 321 within the middle tube 32 by means of a multi-directional swivel 341. The squirrel cage 321 within the middle tube 32 is further connected to the squirrel cage 331 within the other side tube 33 by means of a multi-directional swivel 351. Thus the motor 36 is able to drive and rotate the three squirrel cages 311, 321 and 331. In addition, The motor 36 may also be used to drive the multi-directional swivels 341 and 351 in the universal joints 34 and 35 for further driving and rotating the squirrel cages 321 and 331. Also, the three squirrel cages 311, 321 and 331 may be combined using segmental joining methods. Referring to FIG. 3, the airflow produced during the rotation of the squirrel cages 311, 321 and 331 within the tubes 31, 32 and 33 is discharged through outlets 312, 322 and 332 at the top thereof.

[0015] Referring to FIGS. 4 and 5, reflecting blades 313, 323 and 333 are disposed at the two ends of the tubes 31, 32 and 33 (as reflecting blades in vents of air conditioners) capable of compensating airflow deficiency at corners by adjusting angles of the blades. Referring to FIG. 1, in the jet airflow discharging device 3 according to the invention, the motor 36 drives the squirrel cages 311, 321 and 331 to produce airflow that travels upwards through the outlets 312, 322 and 332 and form an invisible (transparent) air-wall A. The air-wall A separates the air in and out of the air-wall A and forwards the smoke to the suction area B of the smoke exhaust 2, thereby compensating the suction deficiency of the smoke exhaust 2 and further preventing the smoke from dirtying kitchen utensils and harming the health as being inhaled by human lungs.

[0016] In addition, the jet airflow discharging device 3 according to the invention may not only be disposed between the gas stove 1 and other kitchen units but may also be combined with the gas stove 1 or other kitchen units during the production process to become one body.

[0017] Conclusive from the above, a jet airflow discharging device according to the invention is disposed near a kitchen gas stove, such that an invisible air-wall is formed using jet airflow that forwards smoke produced upwards to the suction area of a smoke exhaust, thereby preventing the smoke dirtying kitchen utensils or harming the health as being inhaled by human lungs. It is of course to be understood that the embodiment described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
