Embodiment Construction

[0020] Such as figure 1 , 2 , shown in 3: at the air inlet at the front end of the range hood fan (1) face frame (2), add a negative pressure guide cover, and the negative pressure guide cover is fixedly connected or flexibly connected with the face frame (2).

[0021] The negative pressure guide cover is a bell mouth-shaped hollow body.

[0022] When the negative pressure guide cover is a movable cover, the negative pressure guide cover can be composed of two or more pieces of the inner half cover (3) and the outer half cover (4), and the length of the outer half cover (4) is slightly shorter than that of the inner half cover ( 3), its radian is slightly larger than the inner half cover (3). The end of the inner half cover (3) is provided with an inner half cover fixing ring (10) extending 90 degrees inwardly of the arc, and the end of the outer half cover (4) is provided with an outer half cover fixing ring (11) extending outwards 90 degrees. , The inner and outer half-co...

Abstract

The invention provides a high efficiency smoke evacuation pipeline embedded type smoke ventilator, which is composed of a blower fan and a surface frame; the smoke ventilator is characterized in that a negative pressure guide housing is provided at an air inlet of the front end of the smoke ventilator surface frame, the negative pressure guide housing enables fixed connection or movable connection with the surface frame, the negative pressure guide housing is in a bell mouth hollow shape. The invention employs the above structure, so that the effect of oil smoke suction and elimination of the smoke evacuation pipeline embedded type smoke ventilator is greatly enhanced, energy consumption is reduced, the usage is convenient and the pollution on outdoor environment is minimized.

Description

Technical field: [0001] The invention belongs to an oil fume suction and exhaust equipment, in particular to a pipe-embedded range hood for sucking and exhausting oil fumes in the kitchens of families, restaurants and restaurants. technical background: [0002] The best-selling pipeline embedded range hood in the market (patent number: ZL99115293.X) is the same as other embedded range hoods in use. The utilization rate of pressure is low. The cooking fume exhaust in the kitchen is not sufficient, which cannot meet the requirements of modern families for the kitchen to be green and environmentally friendly. Invention content: [0003] The present invention provides a high-efficiency, energy-saving, and environment-friendly pipe-embedded range hood. The emission effect of soot, [0004] In order to achieve the above object, the technical solution of the present invention is: in order to make the negative pressure generated by the fan of the range hood embedded in the pipe...
