Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a range hood and, more particularly, to such a range hood, which has adjustable wind guides that guide in escaped waste gas for exhaust.




2. Description of the Related Art




In the kitchen, a range hood is suspended above the range for drawing away waste gas. A regular range hood commonly comprises a hood body having one or two suction ports and a fan mounted inside the hood body and controlled to draw waste gas into the hood body toward the exhaust pipe. During operation, a certain amount of waste gas may escape out of the suction port(s). In order to fully carry waste gas away from the range, wing guide means is necessary to guide all waste gas into the suction port(s) of the range hood.




SUMMARY OF THE INVENTION




The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a range hood, quick requires less installation space. It is another object of the present invention to provide a range hood, which has wind guide means to effectively guide waste gas into the body of the range hood for exhaust. It is still another object of the present invention to provide a range hood, which causes a sense of beauty. According to one aspect of the present invention, the range hood comprises a body formed of a bottom panel, a locating plate supported on the bottom panel, a top panel mounted on the locating plate, a front control panel and a rear panel respectively fastened to the top and bottom panels at the front and rear sides, and two wind guides adjustably fastened to the locating plate and protruded over two sides of the bottom panel for guiding escaped waste gas into the inside of the body through suction holes in side flanges of the bottom panel, a wind box mounted in the body to hold a fan for drawing waste gas into the body through a main suction hole in the bottom panel and suction holes in side flanges of the bottom panel, and an exhaust pipe sleeved onto the wind box and extended out of the body for guiding out waste gas from the wind box and the body. According to another aspect of the present invention, the wind guides each have transverse rows of mounting holes mounted with a respective hollow pin and selectively fastened to respectively mounting holes of the top panel and the locating plate by screws.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIGS. 1

,


2


, and


4


, a range hood is shown comprised of a body


1


, a wind box


2


, an exhaust pipe


3


, and a fan


4


. The body


1


comprises a bottom panel


11


, a top panel


12


, a locating plate


13


, two wind guides


14


, a rear panel


15


, and a front control panel


17


. The bottom panel


11


comprises two mounting flanges


111


upwardly curved from two opposite lateral sides thereof and respectively fastened to the locating plate


13


, and a plurality of suction holes


112


disposed in the mounting flanges


111


. A rubber packing strip


16


is sealed in between the bottom panel


11


and the locating plate


13


to prevent leakage of sucked gas. The top panel


12


is fixedly fastened to the locating plate


13


at the top side, having a plurality of mounting holes


121


disposed in four corners and respectively fastened to respective mounting holes


131


of the locating plate


13


by screws


122


. The top panel


12


further comprises a plurality of bottom flanges


123


protruded from the bottom sidewall thereof at the front and rear sides and disposed in contact with the top sidewall of the locating plate


13


. The wing guides


14


are bilaterally connected between the locating plate


13


and the top panel


12


. The rear panel


15


is fixedly fastened to the bottom panel


11


and the top panel


12


at the rear side. The front control panel


17


is fixedly fastened to the bottom panel


11


and the top panel


12


at the front side. Lamps


19


are installed in the bottom panel


11


near the front control panel


17


. A wire gauge filter


18


is in the center opening (the main suction hole) of the bottom panel


11


.




Referring to FIG.


3


and

FIG. 2

again, the wind box


2


holds the fan


4


on the inside. The top side of the wind box


2


is an open side covered with a cover plate


23


and connected to the top panel


12


. A gasket ring


231


is sealed between the wind box


2


and the cover plate


23


. The bottom side of the wind box


2


is fixedly fastened to the locating plate


13


. The rear side of the wind box


2


is fixedly mounted with a positioning frame


21


by welding. The positioning frame


21


has two hook holes


211


. A mounting plate


22


is provided for securing the positioning frame


21


to the wall. The mounting plate


22


has two hooks


221


for hooking in the hook holes


211


to support the wind box


2


on the wall. The exhaust pipe


3


is sleeved onto the wind box


2


and fixedly secured thereto. The exhaust pipe


3


has a certain length. When installed in the wind box


2


, the exhaust pipe


3


has a part extended out of the top panel


12


.




Referring to FIG.


6


and

FIG. 2

again, the wind guides


14


are made of smoothly arched glass plates, each having a plurality of through holes


141


respectively mounted with a respective hollow pin


132


for the passing of the corresponding screws


122


fastened to the mounting holes


121


of the top panel


12


and the respective mounting holes


131


of the locating plate


13


. The mounting holes


121


of the top panel


12


are tapered holes having a diameter gradually reduced in direction toward the locating plate


13


.




Referring to FIG.


7


and

FIGS. 1 and 2

again, when started the fan


4


to suck in waste gas through the wire gauge filter


18


(the main suction hole of the bottom panel


11


), the smoothly arched wind guides


14


guide the escaped waste gas into the suction holes


112


for exhaust. Because the fan


4


is installed in the wind box


2


inside the exhaust pipe


3


, the size of the range hood is minimized. Further, because the wing guides


14


have multiple through holes


141


for fastening to the screws


122


selectively, the wing guides


14


can be fastened to the locating plate


13


and the top panel


12


in one of a series of positions to change the cover area of the range hood.




Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
