Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, an exhaust-free filter range hood includes a housing 1, a fan 2 and a filtering device 3,

[0015] The housing 1 is composed of a bottom chamber 11, a rear air suction chamber 12 and a front air outlet chamber 13, and the fan 2 is arranged at the junction of the rear air suction chamber 12 and the bottom chamber 11; The air inlet is detachably connected; the filter device 3 on the rear suction chamber 12 is opposite to the air outlet 131 of the front air outlet chamber 13 .

[0016] Described filtering device 3 comprises shell 31, orifice plate 32, gac 33 and net 34, and orifice plate 32 is fixed in the shell 31, and gac 33 is arranged in the hole of orifice plate 32, and net 34 is fixed on the front of orifice plate 32; When a large amount of oil stains are adsorbed on the activated carbon 33, the activated carbon can be replaced.

Abstract

The invention relates to an exhaust free filer type smoke exhaust ventilator which comprises a shell, a fan and a filter device, wherein the shell comprises a bottom cavity, a rear air sucking cavity and a front air outlet cavity; the fan is arranged at the junction of the rear air sucking cavity and the bottom cavity; the filter device is detachably connected with an air inlet of the rear air sucking cavity; and the filter device on the rear air sucking cavity is opposited with an air outlet on the front air outlet cavity. Due to the structure of the smoke exhaust ventilator, air exhausted by the front air outlet cavity forms an air layer above a burner to prevent oil smoke from upwards moving, after the oil smoke is filtered by the filter device, the oil smoke enters the rear air sucking cavity, and then air filtered by the filter device is exhausted by the front air outlet cavity. Compared with the prior art, the smoke exhaust ventilator realizes oil-free smoke exhaust and is environmentally friendly.

Description

technical field [0001] The invention relates to a range hood. Background technique [0002] In the current prior art, a range hood includes a casing, a blower fan and an oil net, and a discharge channel and an oil cup are arranged on the casing. The problem is: after the oil fume is filtered by the oil screen, there will still be oil discharged into the room, polluting the environment. Contents of the invention [0003] The object of the present invention is to provide an exhaust-free filter range hood, which not only has the characteristics of not discharging oily fumes to the outside, and is environmentally friendly, but also prevents the oily fumes from spreading indoors. [0004] The present invention is achieved in the following way: a filter-free range hood comprising a casing, a blower fan and a filtering device, [0005] The housing is composed of a bottom cavity, a rear suction cavity and a front outlet cavity, and the fan is arranged at the junction of the rear...
