Therefore, the present invention provides a function that said filter screen may be secured and replaced not only easily but also quickly.
- In order that the present invention may be more fully understood, a preferred embodiment thereof will now be described with reference to the accompanying drawings, in which:
-
FIG. 1 is a stereogram of the range hood according to the preferred embodiment of the present invention. -
FIG. 2 is a stereogram showing the range hood viewed from another angle according to the preferred embodiment of the present invention. -
FIG. 3 is a breakdown drawing of the range hood according to the preferred embodiment of the present invention. -
FIG. 4 is an upward view of the combination that the fixation holder holds the filter screen according to the preferred embodiment of the present invention. -
FIG. 4 a is a sectional view of 4 a-4 a shown inFIG. 4 . -
FIG. 4 b is a sectional view of 4 b-4 b shown inFIG. 4 . -

- Referring to
FIGS. 1 to 3 , the range hood disclosed in the present invention comprises as follows: - A
casing 1 has a concave hollow bottom portion of which the interior is arranged with apartition plate 2 to form ahollow chamber 10. The top surface of saidcasing 1 and the back plate la of saidcasing 1 are respectively provided with afume outlet 11 connecting saidchamber 10. Saidoutlet 11 may be opened or closed according to the work area where the range hood is mounted and the needs of the users. However, one of saidfume outlets 11 must keep open. The bottom surface of saidpartition plate 2 is provided with afume inlet 20. - A
motor 3, of which the top surface is fixed to theaforementioned casing 1, is provided with adrive axle 30 secured to the center of afan 4; saidfan 4 is configured inside theaforementioned chamber 10 and has a bottom end corresponding to saidfume inlet 20. When rotating, saidfan 4 may axially suck fumes into saidchamber 10, and then, by the centrifugal force, the fumes may be exhausted through saidfume outlet 11. - A
protective net 5 arranged under saidfume inlet 20, is provided with an outer margin fastened to the bottom surface of saidpartition plate 2. - A
filter screen 6, which is an activated carbon filter screen for absorbing, filtering and purifying fumes, is arranged under saidprotective net 5. - A fixation holder 7, fashioned into the shape of a trapezoid and configured under said
filter screen 6, provides abottom base 70 which has two sides respectively disposed with apivot pin 71 protruding outward so as to be pivotally connected with ahollow joint 21 of saidpartition plate 2; wherein, saidhollow joint 21 and the body of saidpartition plate 2 are formed in an integral stamping mode. Moreover, said fixation holder 7 is also provided with atop base 72 clasped with a resilient hookedplate 22 of saidpartition plate 2. Said resilient hookedplate 22, having a curved shape, is formed with the body of saidpartition plate 2 in an integral stamping mode. Wherein, the back of said resilient hookedplate 22 is arranged toward saidjoint 21. Themiddle section 73 of said fixation holder 7 may hold saidfilter screen 6. - A
screen cover 8, configured under saidfilter screen 6, as shown inFIG. 5 , has one end placed onto a folded lip lb of the bottom margin of said the back plate 1 a; wherein said foldedlip 1 b is flat folded toward the inner side of thecasing 1. Moreover, the other end of saidscreen cover 8 is arranged with aretractable pin 80 allowed to extend outwards to be inserted into a hole of saidcasing 1 so that saidscreen cover 8 may be secured to saidcasing 1. Wherein, saidretractable pin 80 is controlled by a hand-pull plate 81 to be able to withdraw inwards so as to be unfastened. - Referring to
