Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0015] Such as Figure 1~2 The range hood shown includes a first motor 5, a fume purification filter 2, and the fume purification filter 2 is connected to the first motor 5 through a first connecting shaft 4, and it also includes a fan 3, and a fan center hole is arranged in the middle of the fan 3 10. The first connecting shaft 4 passes through the central hole 10 of the fan and connects to the oil fume purification filter 2 . The oil fume purification filter screen 2 is a mesh structure (such as image 3 shown).

[0016] Such as Figure 4 As shown, the oil fume purification filter screen 2 is provided with a shaft cylinder 13 in the middle, the fan 3 is connected to the outer wall of the shaft cylinder 13 in the circumferential direction, and one end of the first connecting shaft 4 is arranged in the shaft cylinder 13, and is connected with the shaf...

Abstract

The invention discloses a range hood, comprising a first motor, an oil smoke purification filter screen and a fan, wherein the oil smoke purification filter screen is connected with the first motor through a first connecting shaft, the middle part of the fan is provided with a fan center hole, and the first connecting shaft passes through the fan center hole and is then connected with the oil smoke purification filter screen. Since the connecting shaft connected with the oil smoke purification filter screen is provided with the fan, the motor drives the fan to rotate during working of the range hood, so ventilation effects are effectively improved while noise is controlled; the range hood is an environment-friendly range hood.

Description

technical field [0001] The invention belongs to the technical field of kitchen range hoods, and in particular relates to a range hood structure. technical background [0002] The range hood widely used at present is mainly made of casing, air duct, blower fan, check valve, oil collecting and discharging device, lighting device, power switch and power cord etc. The upper part of the inner wall of the traditional range hood shell is provided with a wind wheel. When the range hood is working, the wind wheel rotates under the drive of the motor to form an air negative pressure area. Driven by the motor, the oil fume is filtered, and the oil fume is discharged from the exhaust port after being filtered. Although the range hood with this structure has a good purification effect on the oil fume, due to the poor ventilation effect, the oil fume cannot enter the smoking port very effectively, which affects the oil fume purification rate. Contents of the invention [0003] The pur...
