Description

Heat exhausting fume device

The utility model relates to a range hood, in particular to a heat exhausting fume device with excellent heat exhausting and exhausting efficiency.

Foods produce a large amount of soot in the process of cooking at high temperatures. If not properly drained outside, it will cause health hazards to the human body in the room. In addition, because the soot exhaust gas is not only bad smell, but also contains a lot of harmful substances, the catering business place usually installs a soot processing equipment in the smoke exhausting equipment to reduce the pollution of the soot exhaust gas to the environment.

Referring to FIG. 1 , it is a conventional business smoke exhausting device, and its structural design mainly includes a cooking pedestal 11 , and a plurality of windshields 12 continuously disposed on three sides of the cooking pedestal 11 , and a windshield 12 disposed at the same A hood 13 having a venting opening 131 at the top of the louver 12, and a venting device 14 disposed on the outer top surface of the hood 13 and corresponding to the venting opening 131. The soot generated during the cooking process can be operated by the extraction device 14 in the space surrounded by the windshield 12, and discharged from the air outlet 131.

In order to prevent the oil from dripping, the oil slab is usually placed just below the air outlet 131 (not shown due to the angle of view), but it will affect the ventilation effect. In addition, there is no above the hood 13 The law then directly installs a fume purification accessory (such as an electrostatic fume purifier or a built-in mist-type fume purifying duct), which must be installed on the wall or on the ground, so that it is not only a place but also beautiful. Convenience.

In addition, in general household smoke exhausting equipment, because the horsepower of the exhaust motor is weak, and the windshield is not extended on both sides of the casing, the smoking effect is generally poor, the indoor kitchen tends to be greasy everywhere, and the inside of the hood is not easy. Cleaning, affecting the health of personnel, and causing the cleaning burden of personnel.

Therefore, the object of the present invention is to provide a heat exhausting fume device which is easy to clean and maintain, and has excellent heat exhausting and exhausting efficiency.

Therefore, the novel exhaust heat exhausting fume device is configured to absorb the soot exhaust gas and discharge to the outside, and the exhaust heat exhaust fume device comprises a casing, at least two oil retaining plates, and an air extracting unit.

The casing includes a gas space, at least one support member disposed in the gas space, at least one support member disposed in the gas space, and an exhaust port, the upper support member and the lower portion The supports are located at different heights and are not on the same vertical line.

The oil slingers each have a first engaging portion formed at the upper end, and a second engaging portion formed at the lower end, the oil retaining plates are fastened to the upper supporting member by the first engaging portions And the second engaging portions are disposed on the rear side of the lower support member, and are juxtaposed adjacent to each other, and the oil retaining plates and the casing jointly define a side adjacent to the lower edge of the lower support member. The main air inlet and a secondary air inlet located at the adjacent side of the front edge of the upper support.
