Definitions

  • the present invention relates to a range hood, and more particularly, to a range hood which is capable of resisting the draft coming from all directions and exhausting soot and pollutants, and is suitable for household kitchens, kitchens of restaurants, or other working places producing polluting gases.
  • a conventional range hood in a kitchen scarcely differs from a top-suction style range hood in a working space.
  • this conventional kind of range hood the velocity of airflow flowing upwards is much decreased when the airflow is approaching the air-extraction slot of the range hood in a short distance, and thus the upward extraction force is usually insufficient.
  • the performance of the range hood is much easily liable to the draft caused by people walking by, fans, or the operation of air conditioners.
  • the effective area for confining soot is greatly reduced to a small area. In this way, the soot when being closely adjacent to the air-extraction slot will escape along with the draft, which will jeopardize the health of those who cook in kitchens.
  • range hood having “air curtain” based on aerodynamic principles.
  • the main technical feature of above range hood is to provide an air jet blown in a upward and oblique direction in front of a counter, and provide a air-extraction hood in the shape of a slot above an oven, where the left and right sides of the oven on the counter are left open for the purpose of air supply, so as to form a nearly two-dimensional air curtain by means of the blown and drawn air jets.
  • This flow field conforming to aerodynamic principles is able to have the soot and harmful gases between the oblique air curtain and a rear wall be carried steadily upwards to the air-extraction hood and exhausted.
  • above range hood is indeed capable of confining and exhausting the soot and harmful gases effectively. Besides, it is able to minimize the leakage caused by people walking by or by slight draft with velocity below 20 cm/s.
  • the left and right sides of the oven on the counter are left open and air can be drawn in and supplied so as to form a two-dimensional air curtain facing those who are cooking. In this way, it is able to provide a strong resistance against the interference of the draft in front of the counter.
  • it is quite difficult to completely get rid of the interference of slightly stronger draft coming from all directions, such as the airflows produced by electrical fans or others flowing through door or window from without. This phenomenon will complicate the draft in the kitchens.
  • above range hood having two-dimensional air curtain is required to include simultaneously an air blow device and an air-extraction device. Therefore, it is quite inconvenient to assembly or to replace these components. Besides, since more apparatuses are required, the cost of apparatuses and labor is thus increased.
  • An object of the present invention is to provide a range hood capable of resisting draft, where by providing an elongate air-extraction slot on the bottom of the air-extraction hood and providing a long upright plate respectively below the left and right lateral surfaces of the air-extraction hood, it is able to prevent lateral draft from flowing in and to form an intact upwards-flowing airflow, so as to exhaust soot and harmful gases.
  • Another object of the present invention is to provide a range hood capable of resisting draft, where by providing a long upright plate respectively below the left and right lateral surfaces of the air-extraction hood and providing a guiding structure respectively at the front ends of the two upright plates, when air is drawn into the space below the air-extraction hood through the front ends of the upright plates, it is able to reduce the backflow areas formed by the deviated airflow from the front ends of the left and right upright plates, so as to keep the exhaust airflow flowing smoothly.
  • Another object of the present invention is to provide a range hood capable of resisting draft, where by providing an air blow groove at one end of the air-extraction slot located on the bottom of the air-extraction hood, the upwards blown air can confine the high-temperature expanding gas produced by an air-generation device and guide the high-temperature expanding gas into the elongate air-extraction slot in order to prevent its leakage.
