Description
~1~65Z1 EXHAUST APPARATUS FOR COOKING AND MOUNTING METHOD THEREOF
BACKGROUND OF THE INVENTION
Field of the Invention:
This invention relates to an exhaust apparatus for cooking and a method for mounting the exhaust apparatus.
Description of the Related Art:
In a conventional cooking exhaust apparatus used in a multistoried dwelling house, 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.
In order to dissolve this problem, it needs to enlarge the capacity of the exhaust blower or to provide a means for making a convection of smoke under a smoke inlet of the exhaust blower in the smoke collecting hood.
However, this results in the reduction of the drawing power of the exhaust blower and smoke cannot be sufficiently exhausted. .
SUMMARY OF THE INVENTION
It is an object of this invention to provide a cooking exhaust apparatus which can collect smoke with high efficiency and high safety for use in a kitchen of a multistoried dwelling house or a detached house.
It is another object of this invention to provide a method for easily and quickly mounting the above-described cooking exhaust apparatus in place of an existing conventional exhaust apparatus.
To achieve the above object, a cooking exhaust apparatus according to the present invention 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.
When the above-described cooking exhaust apparatus is mounted in place of an existing conventional exhaust apparatus, an exhausting port of the exhaust blower may be connected to an 217b521 existing exhaust pipe provided in a ceiling.
In case of switching on a range of a cooking equipment mounted on a floor and cooking by using a pan or a gridiron through a trivet, steam, particles of oil, smoke from grilled food and so on (hereinafter, generically referred as "smoke") are generated.
By driving an exhaust blower before cooking, an air within an air chamber is drawn from a downward drawing port of the exhaust blower so that the inside of the air chamber is depressurized and the air may be exhausted to the outdoor through an exhaust pipe provided in the ceiling.
Since 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.
By providing guide plates for rectifying ascending smoke in the smoke collecting hood, 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 z~ ~6~2~
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.
