FR2492951A1 - COOKING EXHAUSTER - Google Patents

Abstract

THE EXHAUSTER ACCORDING TO THE INVENTION IS PROVIDED FOR A COOKING BENCH 1 CARRYING A BURNER. IT INCLUDES AN EXTENSION DIRECTED TO THE TOP 3, WHICH STARTS FROM BENCH 1 IN ITS REAR PART IN CONTACT WITH WALL 5. IT FURTHER INCLUDES A GAS SUCTION PORT 4, SHAPED IN THE UPPER END OF EXTENSION 3, OF THE MEANS OF EXPULSION 8, 9, 10 OF THE GAS TO THE EXTERIOR THROUGH SUCTION PORT 4 AND THROUGH WALL 5, A DUCT 7 CONNECTING BETWEEN THEM ORIFICE 4 AND THE EXHAUST MEANS 8, 9, 10 AND A GUIDE PLATE 6 FROM THE WALL 5 TO THE FRONT OVER THE SUCTION PORT 4 AND THE BURNER. THE INVENTION PREVENTS OIL AND DUST PARTICLES FROM BONDING TO THE SUCTION PORT AND TO THE EXHAUST MEANS.

Description

The invention relates to an enhancer for cooking and more

  especially for a bench or table

  cooker carrying a furnace or burner.

  Conventionally, smoke and other gases

  dredged by a gas oven or gas stove is spreading in the kitchen before being evacuated to the outside.

by a fan.

  A general object of the invention is to provide an enhancer to collect and quickly evacuate these gases before they spread M in the kitchen. According to the invention, there is provided an exhauster for a cooking bench carrying a burner, comprising an extension starting from the bench upwards, at the rear which is in contact with a wall, a gas suction orifice formed in the end of the extension, means for expelling gas through this suction port outwardly through the wall, a conduit connecting the orifice and the expulsion means and a guide plate moving forwards in starting from

  wall over the suction port and the burner.

  A preferred embodiment of the invention will be explained below with reference to the accompanying drawings, in which: FIG. 1 is a perspective view of a cooking apparatus embodying the invention; - Figure 2 is a side view of the apparatus in vertical section; FIG. 3 is a perspective of an enhancer

according to the invention.

  The drawings show a bench or cooktop 1 installed in a kitchen and above which there is a gas stove 2, a gas oven 11 below the stove and a fireplace 12 for the oven, this fireplace being provided with an opening 13 at the back

of the stove 2.

  The bench 1 has an extension directed to the top, 3, at the rear which is in contact with a wall 5 of the kitchen. In the top of the extension 3 is provided a suction port 4 inclining towards the furnace 2. The orifice 4 may have latches 14 to guide the flow of gases. A gas flow guiding plate 6 moves from the wall 5 forward over the orifice

  4, the chimney 12 and the furnace 2.

  The single suction port 4 com through a duct 7 with an exhaust fan 8 provided on the wall 5 to expel gases to the outside through the wall. The fan 8 may have jalousies 15 in its exhaust port for

guide the flow of gas.

  The suction port 4 has the same sectional shape as the intermediate portion of the duct 7 while the exhaust port 10 of the fan 8 has a larger section than the building.

  suction 4 of the intermediate portion of the duct 7.

  For this purpose, the conduit 7 has an end of

  exit 9 of larger section than the intermediate part

duct 7.

  The size of the duct 7 and the fan 8 and the power of the fan 8 are determined so that the time taken for the gases to pass from the suction orifice 4 to the exhaust orifice 10 is less than about 5. the second is for example 3 to 5 seconds, because heated oil particles generated during cooking are chemically modified by water vapor and become tacky in about 15 seconds or more and stick to the inner surfaces of the conduit 7 etc. When the fan 8 is actuated, there is a vacuum inside the outlet 9 of the duct and there occurs, in the duct 7 and the suction port 4, a stream of gas directed to the outlet 9 The exhaust smoke -3- or the gases 16 (FIG. 3) coming from the furnace 2 or the chimney 12 escape to the outside, through the suction orifice 4, the duct 7, the fan 8 and the exhaust port 10 # so quickly that the heated oil particles contained in the smoke do not stick to the inner surfaces of the

  duct 7 and outlet 9 and fan 8.

  Given the fast flow of gas, the heat of the flowing gas does not accumulate inside the duct 7. Given the negative pressure in the duct 7, the liquid particles of the aspirated gas evaporate and expand. . As a result, the gas flowing inside the duct cools down to

about 4o'c.

  In the embodiment described above it is not possible for oil particles and dust to stick to the suction port 4, the duct 7, the fan 8 etc., so that the enhancer remains clean. On the other hand, the gases can be sucked uniformly and the temperature in the conduit 7 can be lowered, so that

  security is improved.
