Definitions

  • This invention relates to an exhaust apparatus for cooking and a method for mounting the exhaust apparatus.
  • a smoke collecting hood which opens out downwardly is arranged just above a gas range of a cooking equipment, and an exhaust blower is mounted within the smoke collecting hood. Therefore, it has been difficult to draw smoke uniformly from the whole area of the downward opening of the hood into the exhaust blower.
  • a cooking exhaust apparatus comprises a smoke collecting hood arranged just above a range of a cooking equipment; an exhaust blower connected to the upper portion of said smoke collecting hood for exhausting smoke generated by the range and collected by said smoke collecting hood; and an air chamber interposed between said smoke collecting hood and said exhaust blower having a tubular body with a lower end inlet connected to an upper exhaust port of said smoke collecting hood and an upper end outlet connected to a lower drawing port of said exhaust blower, the inner diameter of the tubular body being greater than those of the lower end inlet and the upper end outlet.
  • the cooking equipment may be mounted on a floor.
  • the smoke collecting hood may include guide plates for rectifying ascending smoke provided therein.
  • the tubular body of the air chamber may be cylindrical or square.
  • the cooking exhaust apparatus may further comprise a connecting pipe for connecting between the upper exhaust port of the smoke collecting hood and the lower end inlet of the air chamber, the upper portion of said connecting pipe protruding in said air chamber to form an oil sink between the inner wall of the tubular body and the outer wall of the protruded connecting pipe.
  • the upper end of the connecting pipe may be covered by a fire extinguishing net.
  • an exhausting port of the exhaust blower may be connected to an existing exhaust pipe provided in a ceiling.
  • the inner diameter of the tubular body of the air chamber is greater than those of the lower end inlet and the upper end outlet of the air chamber, air existing along the inner wall of the tubular body is led upwards by the air flow from the lower end inlet to the upper end outlet to depressurize the portion. Further, the suction of the blower maintains the depressurised state of the portion along the inner wall of the tubular body to rise the suction power in the lower end inlet.
  • the ascending flow of smoke is promoted. Further, since smoke or flame generated by cooking comes into contact with the guide plates, the plates absorb heat from smoke or flame to prohibit heat from accumulating and the flame will be extinguished. Heat is also absorbed by the fire extinguishing net when the air flow passes therethrough. As a result, remaining flame is extinguished and ascending particles of oil to be scattered will fall into the oil sink formed between the inner wall of the tubular body and the outer wall of the protruded connecting pipe. That is, dripping or ascending of the oil particles is obstructed.
  • the cooking exhaust apparatus according to the present invention can be mounted in each of kitchens of a multistoried dwelling house in place of an existing conventional exhaust apparatus by connecting an exhausting port of the exhaust blower to an existing exhaust pipe provided among the beams.
  • a cooking equipment 2 is located on a floor 1 of a kitchen in a multistoried dwelling house or a detached house in a state of touching a wall 9.
  • a gas or electric range 3 is mounted on the upper surface of the cooking equipment 2, and a smoke collecting hood 4 is arranged just above the range 3.
  • a hanging cupboard Provided at the left and right sides of the hood 4 is a hanging cupboard. Therefore, a vertical cover board 10 is provided in front of the hood 4 on the same vertical plane as a front surface of the hanging cupboard.
  • the smoke collecting hood 4 has a shape of a truncated pyramid tube and is provided with a plurality of guide plates for rectifying ascending smoke 7 which are arranged symmetrically with respect to right and left in a direction of an upper exhaust port 4' of the hood 4.
  • the central one of the plates 7 is the highest, and the farther separated to right and left, the lower the plates 7 are.
  • the plates 7 are made of stainless steel and have a function of absorbing heat.
  • an air chamber 5 having a tubular body with a lower end inlet 5' and an upper end outlet 5''.
  • the lower end inlet 5' is connected and fitted to the upper exhaust port 4' of the hood 4, while the upper end outlet 5'' is connected and fitted to a lower drawing port 6' of an exhaust blower 6.
  • the tubular body of the air chamber 5 may be cylindrical or square and the inner diameter thereof is greater than those of the lower end inlet 5' and the upper end outlet 5''.
  • the lower drawing port 6' of the exhaust blower 6 may be connected to the upper end outlet 5'' of the air chamber 5 through a connecting pipe 10a.
  • a flexible pipe or bellows pipe may be used as the connecting pipe 10a.
  • the exhaust blower 6 may be disposed between a slab 11 and a suspended ceiling 12 and be straightly connected to an exhaust pipe 8 provided in the ceiling.
  • a sirocco fan and the like may be used as the exhaust blower 6.
  • An exhausting port 6'' of the exhaust blower 6 may be straightly connected to a new or existing exhaust pipe 8 provided in the ceiling (Fig. 2), or connected to the exhaust pipe 8 with bending by using a bellows pipe 13 (Figs. 1 and 3 to 5).
  • the exhausting port 6'' of the exhaust blower 6 rather opens to a newly-established ventilation window 14.
  • the upper exhaust port 4' of the hood 4 and the lower end outlet 5' of the air chamber 5 may be formed so as to have square shapes, and a cylindrical connecting pipe 5a may be connected to the lower end outlet 5' such that the upper portion 5a' of the connecting pipe 5a protrudes in the tubular body to form an oil sink a having a doughnut shape between the inner wall of the tubular body and the outer wall of the protruded upper portion 5a' of the connecting pipe 5a, as shown in Fig. 9.
  • the upper end of the protruded upper portion 5a' of the connecting pipe 5a may be covered by a fire extinguishing metal net 22 having a dome shape, as shown in Fig. 9.
  • numeral 15 denotes a motor of the exhaust blower 6, 16 a rotating fan, 17 an outer wall, 18 an outer wall opening of the exhaust pipe 8, 19 a cover for the opening 18, 20 a hanging jig, and 21 a smoke introducing plate.
  • an air chamber is interposed between a smoke collecting hood just above a cooking equipment and an exhaust blower, and the inner diameter of a tubular body of the air chamber is greater than those of a lower end inlet and an upper end outlet of the air chamber. Therefore, the inside of the air chamber is depressurized and the suction power can be increased.
  • Ascending particles of oil are caught into an oil sink to maintain the blower and the exhaust pipe to be clear.
  • a fire extinguishing net also absorbs heat from smoke or flame so that extinguishment of flame is surely done.
